Numbers 33:3-4

Amplified Bible, Classic Edition

³ They set out from Rameses on the fifteenth day of the first month; on the day after the Passover the Israelites went out [of Egypt] with a high hand and triumphantly in the sight of all the Egyptians,

⁴ While the Egyptians were burying all their firstborn whom the Lord had struck down among them; upon their gods also the Lord executed judgments.
