Numbers 33:3-5

American Standard Version

³ And they journeyed 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 a high hand in the sight of all the Egyptians, ⁴ while the Egyptians were burying all their first-born, whom Jehovah had smitten among them: upon their gods also Jehovah executed judgments.

⁵ And the children of Israel journeyed from Rameses, and encamped in Succoth.
