Time Brings About Change

Gen 32:9 Then Jacob prayed, "God of my grandfather Abraham and God of my
father Isaac, hear me! You told me, LORD, to go back to my land and to my
relatives, and you would make everything go well for me.
Gen 32:10 I am not worth all the kindness and faithfulness that you have
shown me, your servant. I crossed the Jordan with nothing but a walking
stick, and now I have come back with these two groups.

During the twenty years that Jacob was away, he changed from being just a
sojourner, to becoming a man of great wealth. He seems to have become
a lot more humble, and he seems to have realized that the value of the
relationships with his family is worth more than the blessings he "cheated"
from his brother Esau. He was now willing to bestow blessing, rather than
receive it, in order to regain that relationship:

Gen 32:16 He divided them into herds and put one of his servants in charge
of each herd. He said to them, "Go ahead of me, and leave a space between
each herd and the one behind it."
Gen 32:17 He ordered the first servant, "When my brother Esau meets you and
asks, 'Who is your master? Where are you going? Who owns these animals in
front of you?'
Gen 32:18 you must answer, 'They belong to your servant Jacob. He sends
them as a present to his master Esau. Jacob himself is right behind us.' "

Esau had also become a man of wealth who had enough of his own, to not have
needed to accept these gifts. He had totally forgiven Jacob during
these years of absence:

Gen 33:4 But Esau ran to meet him, threw his arms around him, and kissed
him. They were both crying.
Gen 33:5 When Esau looked around and saw the women and the children, he
asked, "Who are these people with you?" "These, sir, are the children whom
God has been good enough to give me," Jacob answered.
Gen 33:6 Then the concubines came up with their children and bowed down;
Gen 33:7 then Leah and her children came, and last of all Joseph and Rachel
came and bowed down.
Gen 33:8 Esau asked, "What about that other group I met? What did that
mean?" Jacob answered, "It was to gain your favor."
Gen 33:9 But Esau said, "I have enough, my brother; keep what you have."
