Liturgy do Rodzaju 15:13

Blessed be the One who keeps His promise to Israel, blessed be He; since the Holy One, blessed be He, calculated the end [of the exile,] to do as He said to Avraham, our father, in the Covenant between the Pieces, as it is stated (Genesis 15:13-14), "And He said to Avram, 'you should surely know that your seed will be a stranger in a land that is not theirs, and they will enslave them and afflict them four hundred years. And also that nation for which they shall toil will I judge, and afterwards they will go out with much property.'"
