זוהר בראשית — דף קסג ע”ב

The Zohar explains “they conceived” and “the flocks conceived before the rods” as the heating of the degrees of judgment that watch over the world. Rabbi Hiya comments on “my soul clings to You, Your right hand holds me”: whoever clings to the Holy One, blessed be He, is held by Him and never abandoned. When the channels (rehatim) are filled, all the flocks are watered; Jacob chose the right side and separated his portion from that of the peoples, “he set his flocks by themselves”; he is the summation of the fathers and fixes the evening prayer. Rabbi Abba says that Israel is above those who serve stars and constellations: the former on the side of holiness, the latter on the side of impurity. After the Temple’s destruction, “He drew back His right hand,” and the left grows strong until the Holy One, blessed be He, rebuilds the Temple and removes the spirit of impurity.
