Numbers 33:3-6

33:3 They departed from Rameses in the first month, on the fifteenth day of the first month; on the day after the Passover the Israelites went out defiantly in plain sight of all the Egyptians. 33:4 Now the Egyptians were burying all their firstborn, whom the Lord had killed among them; the Lord also executed judgments on their gods.

33:5 The Israelites traveled from Rameses and camped in Succoth.

33:6 They traveled from Succoth, and camped in Etham, which is on the edge of the wilderness.
