Genesis 30:39

וַיִּֽקַּֽח־לוֹ יַעֲקֹב מַקַּל לִבְנֶה לַח וְלוּז וְעֶרְמוֹן וַיְפַצֵּל בָּהֵן פְּצָלוֹת לְבָנוֹת מַחְשֹׂף הַלָּבָן אֲשֶׁר עַל־הַמַּקְלֽוֹת

And Jacob took him rods of fresh poplar, and of the almond and of the plane-tree; and peeled white streaks in them, making the white appear which was in the rods.

וַיַּצֵּג אֶת־הַמַּקְלוֹת אֲשֶׁר פִּצֵּל בָּרֳהָטִים בְּשִֽׁקֲתוֹת הַמָּיִם אֲשֶׁר תָּבֹאןָ הַצֹּאן לִשְׁתּוֹת לְנֹכַח הַצֹּאן וַיֵּחַמְנָה בְּבֹאָן לִשְׁתּֽוֹת

And he set the rods which he had peeled over against the flocks in the gutters in the watering-troughs where the flocks came to drink; and they conceived when they came to drink.

וְהַכְּשָׂבִים הִפְרִיד יַעֲקֹב וַיִּתֵּן פְּנֵי הַצֹּאן אֶל־עָקֹד וְכָל־חוּם בְּצֹאן לָבָן וַיָּֽשֶׁת־לוֹ עֲדָרִים לְבַדּוֹ וְלֹא שָׁתָם עַל־צֹאן לָבָֽן

And Jacob separated the lambs—he also set the faces of the flocks toward the streaked and all the dark in the flock of Laban— and put his own droves apart, and put them not unto Laban’s flock.

וְהָיָה בְּכָל־יַחֵם הַצֹּאן הַמְקֻשָּׁרוֹת וְשָׂם יַעֲקֹב אֶת־הַמַּקְלוֹת לְעֵינֵי הַצֹּאן בָּרֳהָטִים לְיַחְמֵנָּה בַּמַּקְלֽוֹת

And it came to pass, whensoever the stronger of the flock did conceive, that Jacob laid the rods before the eyes of the flock in the gutters, that they might conceive among the rods;
