Verse 5 is exactly like 57.11.

For verse 6 see 60.5. In 6b Revised Standard Version give help translates the same Hebrew verb translated “give victory” in 60.5. The Masoretic text at the end of verse 6b is answer me; in 60.5 it is “answer us.” It should be noticed that one form of the Hebrew text here has the reading “answer us.”
