Shemot 13:20-22

Orthodox Jewish Bible

²⁰ And they took their journey from Sukkot, and encamped in Etam, at the edge of the midbar.

²¹ And Hashem went before them by day in an ammud anan, to guide them haderech; and by lailah in an ammud eish, to give them ohr; so they could travel yomam valailah (day or night);

²² He took not away the amud heanan by day, nor the ammud haeish by night, from before HaAm.
