Genesis 30:40

40 These lambs Jacob kept separate; and he put his flock in a place by themselves and not with Laban's flock.

Genesis 30:40 Meaning and Commentary

Genesis 30:40

And Jacob did separate the lambs
The ringstraked, speckled, and spotted; and set the faces of the flocks,
that were all white, towards the ringstraked, and all the brown in the flock of Laban;
either to go before those that were all white, that they by looking at them might conceive and bring forth such, which was another artifice of Jacob's to increase his own sheep; or else he set at the water troughs the white sheep on one side of them, and on the opposite side the speckled ones that the same effect might also be produced the more successfully both by the rods and by the speckled lambs: and he put his own flocks by themselves, and put them not unto Laban's
cattle;
partly that they might not be mixed together, but kept distinct, that what was his property might be discerned from Laban's; and partly, lest his spotted ones, being mixed with Laban's white sheep, by continual looking at them, should conceive and bring forth such likewise, and so his flocks be lessened.

Genesis 30:40 In-Context

38 And he put the banded sticks in the drinking-places where the flock came to get water; and they became with young when they came to the water.

39 And because of this, the flock gave birth to young which were marked with bands of colour.

40 These lambs Jacob kept separate; and he put his flock in a place by themselves and not with Laban's flock.

41 And whenever the stronger ones of the flock became with young, Jacob put the sticks in front of them in the drinking-places, so that they might become with young when they saw the sticks.

42 But when the flocks were feeble, he did not put the sticks before them; so that the feebler flocks were Laban's and the stronger were Jacob's.
