“But I will also judge the nation whom they will serve, and afterward they will come out with many possessions.” Gen. 15:14

It is worth noting that this is yet another parallel to Abram’s life;  Abram himself went to Egypt and came away with many possessions (see Gen. 12:16 and 12:20) Here God, in His vision to Abram, explains a similar situation to occur in the life of his descendants.
