Genesis 29:14

This does not mean that Jacob stayed for only a month. He began by staying for a month. After that, he agreed that he would stay for another 7 years. (See verse 20.) And in the end, he stayed for 20 years.

v15 At the end of the month, Laban spoke to Jacob. He said, ‘You are my relative. But that is not a reason that you should serve me without wages. Tell me, what shall your wages be?’ v16 Now Laban had two daughters. The older daughter was called Leah and the younger daughter was called Rachel. v17 Leah’s eyes were gentle but Rachel was beautiful and lovely. v18 Jacob loved Rachel. So he said to Laban, ‘I will serve you for 7 years. My wages shall be your younger daughter Rachel.’ v19 Laban said, ‘It is good that I should give her to you as your wife. That is better than that I should give her to any other man. Stay with me.’ v20 So Jacob served Laban for 7 years in order to earn Rachel. The 7 years seemed to Jacob to be only a few days. That was the effect of his love for her.
