And it came to pass, that in the morning, Behold, it was Leah. If Jacob's deception, even with the veiled bride, may still be difficult to understand, it is easy to perceive in Leah's substitution for Rachel a clear instance of Divine retribution for the imposition he had practiced on his father.
So the Lord oftentimes rewards evil-doers according to their wickedness (cf. 2 Samuel 12:10-12). And he said to Laban (who, Calvin conjectures, had given Jacob a splendid entertainment the night before to make him say nothing about the fraud), What is this thou hast done unto me?
did not I serve with thee for Rachel? wherefore then hast thou beguiled me? It says much for Jacob that he did not seek to repudiate the marriage. Perhaps he saw the hand of God in what had happened, and probably considered that though he had chosen Rachel, God had selected Leah as his wife.
If so, it must be set to Jacob's credit that at the call of God, thus providentially addressed to him, he was prepared to sacrifice his best affections to the claims of religion and duty. It is not Jacob, but Laban, who proposes that he should also marry Rachel.
