Bamidbar 33:3-5

Orthodox Jewish Bible

³ And they departed from Rameses in the first month, on the fifteenth day of the first month; on the day after the Pesach the Bnei Yisroel went out with a yad ramah (upraised hand, i.e., confidently) l’einei kol Mitzrayim.

⁴ For the Mitzrayim buried all their bechor, which Hashem had struck down among them; upon their elohim also Hashem executed shefatim.

⁵ And the Bnei Yisroel set out from Rameses, and encamped in Sukkot.
