Numbers 33:3-7

Now they journeyed from Rameses in the first month, on the fifteenth day of the first month; on the day after the Passover the sons of Israel started out boldly in the sight of all the Egyptians,

while the Egyptians were burying all their firstborn whom the Lord had fatally struck among them. The Lord had also executed judgments against their gods.

Then the sons of Israel journeyed from Rameses and camped in Succoth.

They journeyed from Succoth and camped in Etham, which is on the edge of the wilderness.

Then they journeyed from Etham and turned back to Pi-hahiroth, which faces Baal-zephon; and they camped before Migdol.
