And Jacob {l} took him rods of green poplar, and of the hazel and chesnut tree; and pilled white strakes in them, and made the white appear which was in the rods.

(l) Jacob used no deceit in this for it was God's commandment as he declares in Ge 31:9,11.

Wesley's Notes

30:37 Here is Jacob's policy to make his bargain more advantageous to himself than it was likely to be: and if he had not taken some course to help himself, it would have been an ill bargain indeed; which he knew Laban would never have considered, who did not consult any one's interest but his own. Now Jacob's contrivances were, He set pilled sticks before the cattle where they were watered, that looking much at those unusual party - coloured sticks, by the power of imagination, they might bring forth young ones in like manner party - coloured. Probably this custom was commonly used by the shepherds of Canaan, who coveted to have their cattle of this motly colour. When he began to have a flock of ring - straked and brown, he contrived to set them first, and to put the faces of the rest towards them, with the same design as he did the former. Whether this was honest policy, or no, may admit of a question. Read Ge 31:7 - 16, and the question is resolved.

Jamieson-Fausset-Brown Bible Commentary

37. Jacob took rods, &c.-There are many varieties of the hazel, some of which are more erect than the common hazel, and it was probably one of these varieties Jacob employed. The styles are of a bright red color, when peeled; and along with them he took wands of other shrubs, which, when stripped of the bark, had white streaks. These, kept constantly before the eyes of the female at the time of gestation, his observation had taught him would have an influence, through the imagination, on the future offspring.

Matthew Henry's Concise Commentary

30:25-43 The fourteen years being gone, Jacob was willing to depart without any 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 agree for stated wages with Laban, whose selfishness was very great. And it would appear that he acted honestly, when none but those of the colours fixed upon should be found among his cattle. Laban selfishly thought 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, and 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 nothing 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.
