That led them by the right hand of Moses with his glorious arm, dividing the water before them, to make himself an everlasting name?
That led (them) by the right hand of Moses with his glorious arm. The right hand of Moses, 'stretched out over the Red Sea,' was but the instrument: the arm of God was the real mover (Exodus 15:6; Exodus 14:21).
Dividing the water before them - (Nehemiah 9:11; Psalms 78:13.)
