Numbers 33:6

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.

8They traveled from before Hahiroth, and crossed through the middle of the sea into the wilderness. They went three days’ journey in the wilderness of Etham, and encamped in Marah.
