After these things the word of the LORD came unto Abram in a vision, saying,
Fear not, Abram: I am your shield, and your exceeding great reward.

Because Abraham did not seek recompense from man, he received it from God, as we read in Scripture: “After these words the Lord spoke to Abraham in a vision saying, Fear not, Abraham, I will protect you. Your reward will be exceedingly great.” The Lord is not slow to reward. He is eager to promise, and he gives in abundance, lest any delay cause weak souls to repent of having despised visible things. He pays back, so to speak, at high interest, rewarding with great abundance the one who has not been seduced by the things of this world that were offered to him. .
