Genesis 30:41

41 Therefore when the sheep were ridden in the first time, Jacob put the rods in the water troughs before the eyes of rams, and of ewe sheep, that they should conceive in the sight of the rods. (And so when the sheep were ridden by the stronger rams, Jacob put up the branches in the water troughs before the eyes of the rams, and the ewe sheep, so that they would conceive in front of the branches.)

Genesis 30:41 Meaning and Commentary

Genesis 30:41

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 ( Genesis 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.)

Genesis 30:41 In-Context

39 they should have the rods before their eyes, and they should conceive in [the] sight of the rods. And it was done that in that heat of riding, or engendering, the sheep should behold those rods, and that they should bring forth spotted beasts, and diverse, and besprinkled with diverse colour. (they would have the branches before their eyes, and they would conceive in front of the branches. And so it was done that in the heat of riding, or of begetting, the sheep saw those branches, and later they brought forth beasts that were spotted, and diverse, and besprinkled with diverse colour, like the branches were.)

40 And Jacob separated the flock, and put the rods in the [water] troughs, before the eyes of the rams (And so Jacob separated out the flock, and put up the branches in the water troughs, before the eyes of the rams). Soothly all the white and [the] black were Laban's; soothly all the others were Jacob's; for the flocks were separated (out) betwixt themselves.

41 Therefore when the sheep were ridden in the first time, Jacob put the rods in the water troughs before the eyes of rams, and of ewe sheep, that they should conceive in the sight of the rods. (And so when the sheep were ridden by the stronger rams, Jacob put up the branches in the water troughs before the eyes of the rams, and the ewe sheep, so that they would conceive in front of the branches.)

42 Forsooth when the late mixing, or engendering, and the last conceivings were, Jacob put not (up) those rods; and those that were late engendered, were made Laban's, and those that were of the first time engendered, were Jacob's. (But when the weaker rams mated, Jacob did not put up the branches; and so the weaker offspring were made Laban's, and the stronger ones were made Jacob's.)

43 And Jacob was made full rich, and had many flocks, handmaids, and menservants, camels, and asses. (And Jacob was made very rich, and had many flocks, and male and female slaves, and camels, and donkeys.)
