Bereshis 30:37-39

Orthodox Jewish Bible

³⁷ And Ya’akov took him fresh cut makal (rod, branch) of poplar and of almond and plane tree; and peeled strips of bark in them, and made the lavan (white) appear which was in the maklot (rods, branches).

³⁸ And he set the maklot which he had peeled before the flocks in the small channels of the shikatot mayim (watering troughs) when the tzon came to drink. And since they bred when they came to drink,

³⁹ And the flocks bred before the maklot, and brought forth tzon streaked, speckled, and spotted.
