What does Genesis 31:12 mean?
Jacob is describing a dream given to him by the Lord. In the dream, Jacob saw off-color goats mating with the flock. The angel of God spoke to Jacob in the dream, pointing this out. Then God said to Jacob that the point of the dream was because He had seen all Laban was doing to Jacob. In other words, God was watching and protecting Jacob. He was aware of how Laban was attempting to take advantage of Jacob. The Lord was letting Jacob know He would intervene for Jacob's good.This, finally, is the explanation for why Jacob made such the deal with Laban in the first place to take all the off-color goats as his wages (Genesis 30:31–36). It also explains why Jacob's highly unusual breeding techniques of placing stripped sticks in water troughs turned out to be so supernaturally successful (Genesis 30:37–43). This was not a suggestion that sheep color is affected by sticks; rather, it's proof that God was the one overseeing the entire process from the start.
