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.

Rods of green poplar - לבנה לח libneh lach. The libneh is generally understood to mean the white poplar; and the word lach, which is here joined to it, does not so much imply greenness of color as being fresh, in opposition to witheredness. Had they not been fresh - just cut off, he could not have pilled the bark from them.

And of the hazel - לוז luz, the nut or filbert tree, translated by others the almond tree; which of the two is here intended is not known.

And chestnut tree - ערמון armon, the plane tree, from ערם aram, he was naked. The plane tree is properly called by this name, because of the outer bark naturally peeling off, and leaving the tree bare in various places, having smooth places where it has fallen off. A portion of this bark the plane tree loses every year. The Septuagint translate it in the same way, πλατανος· and its name is supposed to be derived from πλατυς, broad, on account of its broad spreading branches, for which the plane tree is remarkable. So we find the Grecian army in Homer, Il. ii., ver. 307, sacrificing καλῃ ὑπο πλατανιστῳ, under a beautiful plane tree. Virgil, Geor. iv. 146, mentions,

- ministrantem platanum potantibus umbras.

The plane tree yielding the convivial shade.

And Petronius Arbiter in Satyr.: -

Nobilis aestivas platanus diffuderat umbras.

"The noble plane had spread its summer shade."

See more in Parkhurst. Such a tree would be peculiarly acceptable in hot countries, because of its shade.

Pilled white streaks in them - Probably cutting the bark through in a spiral line, and taking it off in a certain breadth all round the rods, so that the rods would appear party-colored, the white of the wood showing itself where the bark was stripped off.

And it came to pass, whensoever the stronger cattle did conceive,.... Whose limbs were well compact, and were strong and healthy:

that Jacob laid the rods before the eyes of the cattle in the gutters,

that they might conceive among the rods; and bring forth party coloured ones, and such as were robust and strong like themselves; and this was another device of Jacob's to get the best of the flock. Aben Ezra thinks this refers to the two seasons of the year, when the flocks conceived; the one was in Nisan, in the spring, and such as were brought on that conception were strong, and therefore Jacob chose to lay the rods in the gutters at that time, that he might have the best cattle; and so the Targum of Jonathan calls these here the forward ones, as it does those in Gen 30:42 we render feeble, the latter ones; which, according to Aben Ezra, conceived in Tisri or September, and what they brought were weak and feeble. (Based on the laws of genetics, Jacob's breeding of the best of the flock would produce higher quality offspring. Ed.)

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.
