Numbers 33:5

3They traveled from Rameses in the first month, on the fifteenth day of the first month; on the next day after the Passover, the children of Israel went out with a high hand in the sight of all the Egyptians,

4while the Egyptians were burying all their firstborn, whom the LORD had struck among them. The LORD also executed judgments on their gods.

5The children of Israel traveled from Rameses, and encamped in Succoth.

6They traveled from Succoth, and encamped in Etham, which is in the edge of the wilderness.

7They traveled from Etham, and turned back to Pihahiroth, which is before Baal Zephon, and they encamped before Migdol.
