Genesis 30:40-41

40 And Jacob did separate the lambs, and set the faces of the flocks toward the ringstraked, and all the brown in the flock of Laban; and he put his own flocks by themselves, and put them not unto Laban's cattle.
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.

Genesis 30:40-41 Meaning and Commentary

INTRODUCTION TO GENESIS 30

This chapter gives an account of Rachel's envy of her sister for her fruitfulness, and of her earnest desire of having children, which she expressed to Jacob in an unbecoming manner, for which he reproved her, Ge 30:1,2, of her giving her maid Bilhah to Jacob, by whom he had two sons, Dan and Naphtali, Ge 30:3-8; and of Leah's giving her maid Zilpah to him, by whom he had two other sons, Gad and Asher, Ge 30:9-13; and of Reuben's mandrakes he found in the field, and the agreement made between Rachel and Leah about them, Ge 30:14-16; and of Leah's bearing Jacob two more sons and one daughter, Ge 30:17-21, and of Rachel's also bearing him a son, whose name was Joseph, Ge 30:22-24; upon which he desires leave of Laban to depart into his own country, his time of servitude being up, Ge 30:25,26; which brought on a new agreement between him and Laban, that for the future he should have all the speckled, spotted, and brown cattle for his service, Ge 30:27-36; and the chapter is concluded with an account of a cunning scheme of Jacob's to increase that sort of cattle, which succeeded, and by which he became rich, Ge 30:37-43.
