The Prophetic VOW of Increase 37 Now Jacob took for himself rods of green poplar and of the almond and chestnut trees, peeled white strips in them, and exposed the white which was in the rods. 38 And the rods which he had peeled, he set before the flocks in the gutters, in the watering troughs where the flocks came to drink, so that they should conceive when they came to drink. 39 So the flocks conceived before the rods, and the flocks brought forth streaked, speckled, and spotted. 40 Then Jacob separated the lambs, and made the flocks face toward the streaked and all the brown in the flock of Laban; but he put his own flocks by themselves and did not put them with Laban’s flock.
41 And it came to pass, whenever the stronger livestock conceived, that Jacob placed the rods before the eyes of the livestock in the gutters, that they might conceive among the rods. 42 But when the flocks were feeble, he did not put them in; so the feebler were Laban’s and the stronger Jacob’s. 43 Thus the man became exceedingly prosperous, and had large flocks, female and male servants, and camels and donkeys. Genesis 30:37-43
Then Jacob awoke from his sleep and said, “Surely the LORD is in this place, and I did not know it.” 17 And he was afraid and said, “How awesome is this place! This is none other than the house of God, and this is the gate of heaven!”
18 Then Jacob rose early in the morning, and took the stone that he had put at his head, set it up as a pillar, and poured oil on top of it. 19 And he called the name of that place Bethel; but the name of that city had been Luz previously. 20 Then Jacob made a vow, saying, “If God will be with me, and keep me in this way that I am going, and give me bread to eat and clothing to put on, 21 so that I come back to my father’s house in peace, then the LORD shall be my God. 22 And this stone which I have set as a pillar shall be God’s house, and of all that You give me I will surely give a tenth to You.” Genesis 28:16-22
