Genesis 30:37-39

Lexham English Bible

³⁷ Then Jacob took fresh branches of poplar, almond, and plane trees and peeled white strips on them, exposing the white which was on the branches. ³⁸ And he set the branches that he had peeled in front of the flocks, in the troughs and in the water containers. And they were in heat when they came to drink. ³⁹ And the flocks mated by the branches, so the flocks bore streaked, speckled, and spotted.
