Here is Jacob's honest policy to make his bargain more advantageous to himself than it was likely to be. If he had not taken some course to help himself, it would have been a bad bargain indeed, which he knew Laban would never consider, or rather would be well pleased to see him a loser by, so little did Laban consult any one's interest but his own. Now Jacob's contrivances were, 1. To set peeled 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, Gen 30:37-39. Probably this custom was commonly used by the shepherds of Canaan, who coveted to have their cattle of this motley colour. Note, It becomes a man to be master of his trade, whatever it is, and to be not only industrious, but ingenious in it, and to be versed in all its lawful arts and mysteries; for what is a man but his trade? There is a discretion which God teaches the husbandman (as plain a trade as that is), and which he ought to learn, Isa 28:26. 2. When he began to have a stock of ringstraked and brown, he contrived to set them first, and to put the faces of the rest towards them, with the same design as in the former contrivance; but would not let his own, that were of one colour, Gen 30:40. Strong impressions, it seems, are made by the eye, with which therefore we have need to make a covenant. 3. When he found that his project succeeded, through the special blessing of God upon it, he contrived, by using it only with the stronger cattle, to secure to himself those that were most valuable, leaving the feebler to Laban, Gen 30:41, Gen 30:42. Thus Jacob increased exceedingly (Gen 30:43), and grew very rich in a little time. This success of his policy, it is true, was not sufficient to justify it, if there had been any thing fraudulent or unjust in it, which we are sure there was not, for he did it by divine direction (Gen 31:12); nor was there any thing in the thing itself but the honest improvement of a fair bargain, which the divine providence wonderfully prospered, both in justice to Jacob whom Laban had wronged and dealt hardly with and in pursuance of the particular promises made to him of the tokens of the divine favour, Note, Those who, while their beginning is small, are humble and honest, contented and industrious, are in a likely way to see their latter end greatly increasing. He that is faithful in a little shall be entrusted with more. He that is faithful in that which is another man's shall be entrusted with something of his own. Jacob, who had been a just servant, became a rich master.

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.

And when the cattle were feeble, he put them not in,.... Or "when covered", as Menachem, that is, with wool, and so not so desirous of copulation with the males, nor so fit and strong for generation; and therefore he put not in the rods into the gutters, partly that he might have none feeble in his flock, and partly that he might not spoil Laban of his whole flock, strong and weak:

so the feebler were Laban's, and the stronger Jacob's; not only his flocks became more numerous than Laban's, but were a better quality.

watering troughs--usually a long stone block hollowed out, from which several sheep could drink at once, but sometimes so small as to admit of only one drinking at a time.
