Continuing a chronological Bible study:
David had just spared Saul's life when he came into the cave where David was hiding. After they spoke to one another, Saul went back to his palace, and David went back to his hidden stronghold. He composed this psalm after that event.
(Psalm 57:1) (To the chief Musician, Altaschith, Michtam of David, when he fled from Saul in the cave) Be merciful to me, O God, be merciful to me, for my soul trusts in You; yea, in the shadow of Your wings will I make my refuge, until calamities have passed by.
Altaschith meant literally "do not destroy," so perhaps this was David's instruction to the chief musician who would later put this psalm to music. Michtam, as has been discussed before has an unknown meaning, but it is a name David gave to some of his psalms. It comes from a root word meaning "to carve or engrave," so it may have meant a psalm of significance that David specifically wanted engraved to be remembered always.
David asked that the Lord be merciful to him for he trusted in Him. He had nowhere else to go; there was no one he could rely on but God. His only protection was in the shadow of the Lord's wings, using an image of a mother hen protecting her young, so there he desired to stay until his troubles passed.
(2) I will cry to God most high, to God who performs for me. (3) He shall send from heaven and save me from the reproach of him who would swallow me up. Selah. God shall send forth His mercy and His truth.
David would cry out to the most high God, exalted above all. The original word "gamar" that was transcribed as "performs" more completely meant "come to an end, complete, perfect." David trusted that his help would only come from heaven above, not from any man nor from himself. Only God could save him from Saul and bring his troubles to an end. Selah meant a pause. David had faith that God would send forth His mercy in saving him, and faith in His truth in all the promises He made. God had said that David would be king, so he had faith that he would be brought through all his troubles by God so that he would indeed, be king.
(4) My soul is among lions; I lie among them who are set on fire, the sons of men whose teeth are spears and arrows, and their tongue a sharp sword.
David felt surrounded by men fierce and savage as lions. He was among those burning with rage, not beasts, but men whose spears and arrows were like the teeth of wild beasts. Their tongues were like sharp swords in that they cut him with their slander and lies. It is evident that although he had talked his way out of the last encounter with Saul when he showed him he had spared his life, he did not trust Saul and surely expected him to continue to pursue him.
(5) Be exalted, O God, above the heavens, Your glory above all the earth.
I believe David's point was that he wished the Lord to show how He was exalted above all the earth and the heavens by saving him as only He could and having the glory of God in his deliverance be observed by all.
(6) They have prepared a net for my steps; my soul is bowed down; they have dug a pit before me, into the midst where they have fallen. Selah.
David knew his enemies had laid traps for him, and because of that, he was depressed and just tired. I know he had not lost all hope and faith as he continued to say that his enemies had laid traps in which they themselves had fallen. Disheartened though he might be, David recalled what the Lord had done for him. Saul had hunted David, but the Lord had delivered Saul to David.
(7) My heart is fixed, O God, my heart is fixed; I will sing and give praise. (8) Awake, my glory! Awake, psaltery and harp! I will awake early.
However down and tired he was, David intended to keep his heart fixed on God, and of Him, he would sing and give praise. And with that purpose, he revived himself with calls to awaken his soul. He called on musical instruments to make this a hymn of praise. David may have meant that he intended to wake up early with songs of praise, but as the original word transcribed as "early" literally meant "dawn," I believe his point was that he would wake the dawn with his joyous singing.
(9) I will praise You, O Lord, among the people; I will sing to You among the nations. (10) For Your mercy is great to the heavens and Your truth to the clouds.
David vowed to always praise the Lord among the people and sing His praises to all the nations because of His exceedingly great mercy and truth, greater and higher than the highest heights that man could conceive of, the clouds and the heavens.
(11) Be exalted, O God, above the heavens, Your glory above all the earth.
As a matter of fact, David wished the Lord to be exalted even above the heavens with His glory above all the earth and above all angels in heaven.
Once again David had composed a psalm when he felt depressed that began with his complaints which led him to prayer which led to faith in God that led him to rejoicing in God. It is a wonderful model for what we should do when we are feeling persecuted and depressed. After all, the Lord inhabits the praises of His people (Psalm 22:3). Perhaps David intended this psalm to be a model prayer, and that is why he called it a michtam.
As Psalm 108 began with some of the same words which ended Psalm 57, it is reasonable to assume David may have composed it at the same time.
(Psalm 108:1) (A Song, Psalm of David) O God, my heart is fixed; I will sing and give praise, even with my glory.
In Psalm 57, David had said his heart was fixed on the Lord and that he would sing and give praise to the Lord (Psalm 57:7). Then he called upon his soul to awaken, as well as musical instruments to make his psalm a hymn of praise. He composed this psalm, calling it a song. It does seem like this is the song he had rallied his soul (his glory) to sing.
(2) Awake, psaltery and harp; I will awake early. (3) I will praise You, O Lord among the people, and I will sing praises to You among the nations.
David repeated the same words of Psalm 57 in this song. He called on musical instruments and himself to wake early or perhaps he meant to wake the dawn. He would praise the Lord among all the people and sing His praises among the nations.
(4) For Your mercy is great above the heavens and Your truth to the clouds. (5) Be exalted, O God, above the heavens and Your glory above all the earth!
Once again, David declared that the Lord's great mercy and truth were greater and higher than the highest heights that man could conceive of, the clouds and the heavens. David cried out in song that he wished the Lord to be exalted even above the heavens with His glory above all the earth and above all angels in heaven.
(6) That Your beloved may be delivered; save with Your right hand and answer me.
His prayer would seem to be that the Lord deliver him from his persecution by Saul. He implored the Lord to answer his prayer and save him. However, Albert Barnes pointed out in his commentary on the Bible, that, "The word rendered 'beloved,' and the verb rendered 'may be delivered,' are both in the plural number, showing that it is not an individual that is referred to, but that the people of God are intended." Indeed, this same song was sung in Psalm 60, referring to God's people.
(7) God has spoken in His holiness; I will rejoice, I will divide Shechem and mete out the valley of Succoth.
God had spoken prophecies concerning David through His prophet Samuel, and he would rejoice in those. If David's prayer in Psalm 57 is what led him to faith and then to rejoicing and singing, the effects continued to grow as he now proclaimed the things he would do as king. Enemies had to be dislodged from Israel's territory, and lands properly settled and managed, in Shechem on the west side of the Jordan River, as well as in Succoth on the east.
(8) Gilead, mine; Manasseh, mine; Ephraim also the strength of my head; Judah, my lawgiver;
As David continued, it is obvious he spoke by inspiration of the Holy Spirit of God, as these words more accurately belong to the Lord. David claimed them as king of Israel. Gilead and Manasseh already belonged to Israel. Ephraim had been blessed by God with battle skills and the strength of a firstborn bull (Deuteronomy 33:17). 1 Chronicles 12:30 spoke of Ephraim as "mighty men of valor, famous throughout the house of their fathers." Ephraim was known for its military prowess and significant numbers and was considered the strength of Israel. Judah was the lawgiver, and the king's scepter was given to David who was from the tribe of Judah, and the scepter continued in that tribe until the Messiah came, as prophesied by Jacob in Genesis 49:10.
(9) Moab, my washpot; over Edom will I cast out my shoe; over Philistia I will triumph.
God through David would have dominion over Moab and Edom, and they would be as insignificant as a washpot or a shoe cast upon the floor. He would triumph over Philistia.
(10) Who will bring me into the strong city? Who will lead me into Edom?
Who would bring David into the strong city yet unconquered? Who would lead him into Edom which was yet to be conquered?
(11) Not, O God, have cast us off? And will not You, O God, go forth with our hosts?
Obviously, it would be only God who would lead David. However, the wording of this verse is rather difficult. I wrote it just as it would be without the KJV's added words for better understanding. The KJV and other versions would have it read, "Is it not You, O God, who cast us off?" To me, it doesn't sound like language David would be using at this point, if David did indeed write this song at this time. If it was written at this time, but was directed by inspiration of God, or was actually written at a different time, it certainly could reflect a time when it felt like God had cast him or Israel off. However, David would have faith that God surely would lead them.
However, if not written with the KJV's "helping" words that might possibly not form the right context, could David possibly be saying that God surely would not have cast off His people or him, David? That seems to fit this time and place better, in my opinion. But either way, David has great faith that the Lord will lead him and Israel, no matter what!
(12) Give us help from trouble, for vain the help of man.
David asked the Lord to help His people out of their troubles, as only He could. Mere men will always disappoint and be essentially useless, but God is where our real help comes from.
(13) Through God we shall do valiantly, for He shall tread down our enemies.
Through God, His people were and are now able to do wondrous things. David was confident that God would tread down his enemies. This was a prophecy that was fulfilled to David, but it remains true for the followers of the Son of David, Jesus Christ.
