Genesis 15:12 WBT

¹⁰  And he took to him all these, and divided them in the midst, and laid each piece one against another: but the birds he did not divide.

¹¹  And when the fowls came down upon the carcases, Abram drove them away.

¹²  And when the sun was going down, a deep sleep fell upon Abram; and lo, a horror of great darkness fell upon him.

¹³  And he said to Abram, Know certainly that thy seed shall be a stranger in a land [that is] not theirs, and shall serve them; and they shall afflict them four hundred years;

¹⁴  And also that nation which they shall serve, will I judge: and afterward shall they come out with great substance.
