To the chief Musician on Neginoth, A Psalm or Song. God be merciful unto us, and bless us; and cause his face to shine upon us; Selah. God be merciful unto us - Show the Jewish people thy mercy, bless them in their bodies and souls and give a full evidence of thy approbation. This is nearly the same form of blessing as that used Numbers 6:25 (note), where see the notes.
