God's plan is beyond our mind and vision

Genesis 29:1-35
Ruben: means See. a son
Simeon sounds like the Hebrew for heard.
Levi sounds like the Hebrew for attached
Judah sounds like the Hebrew for praise.
Jacob said to Laban, "What is this you have done to me? Did I not serve with you for Rachel: Why then have you deceived me?"
Jacob went in to Rachel also, and he loved Rachel more than Leah, and served Laban for another seven years.
These three chapters 29~31 cover the 20 years of Jacob's exile: 14 years' service for his two wives, six for flocks of his own. The years hold little joy for Jacob, who meets a crooked dealer after his own kind in his uncle Laban. The deceit over Leah leads to an intolerable home life.
The unloved wife hopes with each new son to win her husband's affection.
Why?
Jacob offers service in place of the usual marriage gift. Laban is not slow to exploit the generosity of the offer. The gift of a slave-girl to his daughter may have been part of the dowry(嫁妝).
Although Jacob may have despised Leah, God did not. She became the mother of Levi(the family line of the priests), and of Judah(the royal line)
Jacob deceived his brother Esau, then he was deceived by his uncle, he served Laban for another seven years.
God has his plan on Jacob, so he may has many sons as his inheritance.
20 years exiled to Jacob made him numerable properties.
How?
People under suffer but it may be the blessing from the Lord to his future life. God's plan is beyond our mind and vision.
