The Mighty God Who Delivers Us Victoriously (vv. 5-11). David used these same vivid images in 18:8-9, 14-17, 45, and 50. The Jewish people did not forget God’s dramatic appearance at Mount Sinai (Ex. 19:18-25; 20:18-21), but here the mountains and “great waters” seem to stand for the enemies of Israel (104:32; Isa. 8:7; 59:19; 64:1-5; Mic. 1:4; Nah. 1:5; Hab. 3:10). The “strange children” of verse 7 are the outsiders who attacked Israel, the “aliens and foreigners.” Some of them also tried to get into the nation and cause trouble (v. 11). They told lies and took oaths they never meant to keep. When they lifted their right hand in an oath, it was only deception. As he contemplated God’s power and mercy, David sang a new song to the Lord (see 33:3), for he had experienced God’s help in a new way, learned afresh the wonderful character of the Lord, and was making a new beginning as king of the nation. The plural “kings” refers to David’s successors.
