Numbers 33:4-8

For the Egyptians buried all their firstborn, which the LORD had smitten among them: upon their gods also the LORD executed judgments.

And the children of Israel removed from Rameses, and pitched in Succoth.

And they departed from Succoth, and pitched in Etham, which is in the edge of the wilderness.

And they removed from Etham, and turned again unto Pi-hahiroth, which is before Baal-zephon: and they pitched before Migdol.

And they departed from before Pi-hahiroth, and passed through the midst of the sea into the wilderness, and went three days’ journey in the wilderness of Etham, and pitched in Marah.
