Tehillim 77:18-20

Orthodox Jewish Bible

^18 (19) The voice of Thy thunder was in the galgal (whirlwind); the lightning lit up the tevel (world); ha’aretz trembled and quaked.

^19 (20) Thy derech is in the yam (sea), and Thy path is through the mayim rabbim (great waters), and Thy footsteps are not to be discerned.

^20 (21) Thou didst lead Thy people like a tzon (flock) by the yad Moshe and Aharon.
