Genesis 30:36

33 and my righteousness hath answered for me in the day to come, when it cometh in for my hire before thy face; -- every one which is not speckled and spotted among [my] goats, and brown among [my] lambs -- it is stolen with me.`

34 And Laban saith, `Lo, O that it were according to thy word;`

35 and he turneth aside during that day the ring-straked and the spotted he-goats, and all the speckled and the spotted she-goats, every one that [hath] white in it, and every brown one among the lambs, and he giveth into the hand of his sons,

36 and setteth a journey of three days between himself and Jacob; and Jacob is feeding the rest of the flock of Laban.

37 And Jacob taketh to himself a rod of fresh poplar, and of the hazel and chesnut, and doth peel in them white peelings, making bare the white that [is] on the rods,

38 and setteth up the rods which he hath peeled in the gutters in the watering troughs (when the flock cometh in to drink), over-against the flock, that they may conceive in their coming in to drink;

39 and the flocks conceive at the rods, and the flock beareth ring-straked, speckled, and spotted ones.
