Genesis 30:41 And it came to pass, whensoever the stronger cattle did conceive, that Jacob laid the rods before the eyes of the cattle in the gutters, that they might conceive among the rods.

41 And it came to pass, whensoever the stronger cattle did conceive, that Jacob laid the rods before the eyes of the cattle in the gutters, that they might conceive among the rods. 42 But when the cattle were feeble, he put them not in: so the feebler were Laban's, and the stronger Jacob's. 43 And the man increased exceedingly, and had much cattle, and maidservants, and menservants, and camels, and asses.
