Notice that Psalm 58:3 references the word, gods, with a lower case g. Hmmmm.
1 [Psalm 57] Each of the two equal strophes contains a prayer for rescue from enemies, accompanied by joyful trust in God (Psalm 57:2-5, 7-11). The refrain prays that God be manifested as saving (Psalm 57:6, 11[12]). Psalm 108 is nearly identical to part of this psalm (Psalm 57:8-11 = Psalm 108:2-6).
2 [1] Do not destroy: probably the title of the melody to which the psalm was to be sung.
3 [2] The shadow of your wings: probably refers to the wings of the cherubim (powerful winged animals) whose wings spread over the ark in the inner chamber of the temple (1 Kings 6:23-28).
4 [9] I will wake the dawn: by a bold figure the psalmist imagines the sound of music and singing will waken a new day.
1 [Psalm 58] A lament expressing trust in God's power to dethrone all powers obstructing divine rule of the world. First condemned are "the gods," the powers that were popularly imagined to control human destinies (Psalm 58:2-3), then "the wicked," the human instruments of these forces (Psalm 58:4-6). The psalmist prays God to prevent them from harming the just (Psalm 58:7-10). The manifestation of justice will gladden the just; they will see that their God is with them (Psalm 58:11). The psalm is less concerned with personal vengeance than with public vindication of God's justice now.
2 [1] Do not destroy: probably the title of the melody to which the psalm was to be sung.
3 [2] Gods: the Bible sometimes understands pagan gods to be lesser divine beings who are assigned by Israel's God to rule the foreign nations. Here they are accused of injustice, permitting the human judges under their patronage to abuse the righteous. Cf Psalm 82.
4 [5-6] The image is that of a poisonous snake that is controlled by the voice or piping of its trainer.
5 [9] A snail that oozes away: empty shells suggested to ancients that snails melted away as they left a slimy trail.
