God be merciful unto us, and bless us; and cause his face to shine upon us; Selah.
Psalms 67:1-7.-Prayer for God's mercy upon God's people, that so His way may be known to all nations; also that His righteous reign may come upon earth to the joy of the nations (Psalms 67:1-4); as the result of the praises of all peoples, the earth shall yield her increase, and God shall bless us (Psalms 67:5-7). 'Elohiym (H430) is used throughout, as appropriate to the recognition of the God of the whole earth by all.
God be merciful unto us, and bless us; and cause his face to shine upon us - literally, 'with us;' implying His presence with us as our source of blessedness. The allusion is to the Mosaic blessing, Numbers 6:24-26 (cf. Psalms 4:6; Psalms 31:16). Accordingly the Psalmist here speaks of God, and not until the 2nd verse speaks to God. Compare also the manifold blessing, Deuteronomy 28:1-14.
