Ge 32:3 Then Jacob sent messengers before him to Esau his brother in the land of Seir, the country of Edom.

4 And he commanded them, saying, "Speak thus to my lord Esau, 'Thus your servant Jacob says: "I have dwelt with Laban and stayed there until now.

5 "I have oxen, donkeys, flocks, and male and female servants; and I have sent to tell my lord, that I may find favor in your sight."'"

6 Then the messengers returned to Jacob, saying, "We came to your brother Esau, and he also is coming to meet you, and four hundred men are with him."

7 So Jacob was greatly afraid and distressed; and he divided the people that were with him, and the flocks and herds and camels, into two companies.

8 And he said, "If Esau comes to the one company and attacks it, then the other company which is left will escape."

9 Then Jacob said, "O God of my father Abraham and God of my father Isaac, the LORD who said to me, 'Return to your country and to your family, and I will deal well with you':

10 "I am not worthy of the least of all the mercies and of all the truth which You have shown Your servant; for I crossed over this Jordan with my staff, and now I have become two companies.

11 "Deliver me, I pray, from the hand of my brother, from the hand of Esau; for I fear him, lest he come and attack me and the mother with the children.

12 "For You said, 'I will surely treat you well, and make your descendants as the sand of the sea, which cannot be numbered for multitude.'"

13 So he lodged there that same night, and took what came to his hand as a present for Esau his brother:

14 two hundred female goats and twenty male goats, two hundred ewes and twenty rams,

15 thirty milk camels with their colts, forty cows and ten bulls, twenty female donkeys and ten foals.

16 Then he delivered them to the hand of his servants, every drove by itself, and said to his servants, "Pass over before me, and put some distance between successive droves."

17 And he commanded the first one, saying, "When Esau my brother meets you and asks you, saying, 'To whom do you belong, and where are you going? Whose are these in front of you?'

18 "then you shall say, 'They are your servant Jacob's. It is a present sent to my lord Esau; and behold, he also is behind us.'"

19 So he commanded the second, the third, and all who followed the droves, saying, "In this manner you shall speak to Esau when you find him;

20 "and also say, 'Behold, your servant Jacob is behind us.'" For he said, "I will appease him with the present that goes before me, and afterward I will see his face; perhaps he will accept me."

21 So the present went on over before him, but he himself lodged that night in the camp.

Moses is trying to show to his original Israelite readers Jacob's example with regards his dealings with his brother Esau, who later became the nation of Edom. Israel was not to be hostile against Edom.
De 2:4 Command you the people, saying, You are to pass through the border of your brothers the children of Esau, who dwell in Seir; and they will be afraid of you: take good heed to yourselves therefore;
5 don't contend with them; for I will not give you of their land, no, not so much as for the sole of the foot to tread on; because I have given Mount Seir to Esau for a possession.

Moses is also showing his original Israelite readers the importance of restituting a brother whom they have offended. 

Ex 22:3 "If the sun has risen on him, there shall be guilt for his bloodshed. He should make full restitution; if he has nothing, then he shall be sold for his theft.
4 "If the theft is certainly found alive in his hand, whether it is an ox or donkey or sheep, he shall restore double.

Lastly, Moses is showing them that whatever blessings, privileges and protection they have received and will receive from God, it was all because of God's grace. Just as Jacob was not deserving of all the mercies he received from God so Israel was not deserving of all the blessings, privileges and protection they enjoyed.
