Shemot 14:20-22

Orthodox Jewish Bible

²⁰ And it came between the machaneh Mitzrayim and the Machaneh Yisroel; there was the anan bringing choshech to the Egyptians, but bringing light by night to Yisroel; so that none came near the other, kol halailah.

²¹ Then Moshe stretched out his yad over the yam; and Hashem caused the yam to go back by a strong east wind all that night, so that the yam was made dry land, and the mayim were divided.

²² And the Bnei Yisroel then went into the middle of the yam upon the yabashah (dry land); and the mayim were a chomah (wall) unto them on their right, and on their left.
