Exodus 12:40 WBT

³⁸  And a mixed multitude went up also with them; and flocks, and herds, [even] very many cattle.

³⁹  And they baked unleavened cakes of the dough which they brought from Egypt, for it was not leavened: because they were driven from Egypt, and could not tarry, neither had they prepared for themselves any victuals.

⁴⁰  Now the sojourning of the children of Israel who dwelt in Egypt, [was] four hundred and thirty years.

⁴¹  And it came to pass, at the end of the four hundred and thirty years, even the same day it came to pass, that all the hosts of the LORD departed from the land of Egypt.

⁴²  It [is] a night to be much observed to the LORD, for bringing them out from the land of Egypt: this [is] that night of the LORD to be observed by all the children of Israel in their generations.
