God blessed Jacob even though Laban was deceitful. Jacob cleverly used selective breeding to grow his flock. He followed the traditional belief that peeled sticks could affect the type of animals born.
The peeled branches seemed to help his animals produce streaked and spotted offspring. Jacob later admitted that God had helped him succeed (31:7–12). Jacob ended up with stronger animals, while Laban got the weaker ones (30:41–42).
