Numbers 33:3-7

And they departed from Rameses in the first month, on the fifteenth day of the first month; on the morrow after the passover the children of Israel went out with an high hand in the sight of all the Egyptians.

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.
