SEV Biblia, Chapter 30:38
Y puso las varas que había mondado en las pilas, en los abrevaderos del agua donde las ovejas venían a beber, delante de las ovejas, las cuales se calentaban viniendo a beber.
Clarke's Bible Commentary - Genesis 30:38
Verse 38. And he set the rods which he had pilled before the flocks] It has long been an opinion that whatever makes a strong impression on the mind of a female in the time of conception and gestation, will have a corresponding influence on the mind or body of the fetus. This opinion is not yet rationally accounted for. It is not necessary to look for a miracle here; for though the fact has not been accounted for, it is nevertheless sufficiently plain that the effect does not exceed the powers of nature; and I have no doubt that the same modes of trial used by Jacob would produce the same results in similar cases. The finger of God works in nature myriads of ways unknown to us; we see effects without end, of which no rational cause can be assigned; it has pleased God to work thus and thus, and this is all that we know; and God mercifully hides the operations of his power from man in a variety of eases, that he may hide pride from him. Even with the little we know, how apt are we to be puffed up! We must adore God in a reverential silence on such subjects as these, confess our ignorance, and acknowledge that nature is the instrument by which he chooses to work, and that he performs all things according to the counsel of his own will, which is always infinitely wise and infinitely good.
Matthew Henry Commentary
Verses 25-43 - The fourteen years being gone, Jacob was willing to depart without an provision, except God's promise. But he had in many ways a just claim on Laban's substance, and it was the will of God that he should be provided for from it. He referred his cause to God, rather than agre for stated wages with Laban, whose selfishness was very great. And it would appear that he acted honestly, when none but those of the colour fixed upon should be found among his cattle. Laban selfishly though that his cattle would produce few different in colour from their own Jacob's course after this agreement has been considered an instance of his policy and management. But it was done by intimation from God, an as a token of his power. The Lord will one way or another plead the cause of the oppressed, and honour those who simply trust his providence. Neither could Laban complain of Jacob, for he had nothin more than was freely agreed that he should have; nor was he injured but greatly benefitted by Jacob's services. May all our mercies be received with thanksgiving and prayer, that coming from his bounty they may lead to his praise __________________________________________________________________
