Numbers 33:3-5

Revised Standard Version

³ They set out from Ram′eses in the first month, on the fifteenth day of the first month; on the day after the passover the people of Israel went out triumphantly in the sight of all the Egyptians, ⁴ while the Egyptians were burying all their first-born, whom the Lord had struck down among them; upon their gods also the Lord executed judgments.

⁵ So the people of Israel set out from Ram′eses, and encamped at Succoth.
