Abraham sent his servant back into the homeland of Haran and Mesopotamia to get a wife for Isaac. This woman will be asked to make a decision similar to Abraham's when he left the homeland to obey God and pursue the future plan of God.

The servant is told explicitly in Genesis 24:6 that under absolutely no condition is Isaac to return back into Haran or to the Land of the Chaldeans. Abraham literally said:

“Take my son back there? Absolutely not!”

Abraham is fully aware of the difficulty of this assignment given to his servant. Abraham realizes there will be obstacles such as family ties, inheritance issues, emotional connections, and much more, but he also knows that God has made a promise and that God is working a plan.  Because of this knowledge of God's promise, Abraham has been able to live his life following God. Abraham recites his life of commitment to God’s promise and then makes a logical conclusion: since God had made this promise - “To your offspring I will give this land" - then, God must surely be planning on Abraham’s son, Isaac, continuing and prospering in the Promised Land.

With that knowledge and confidence (or, faith) Abraham reasons that God will provide the wife for his son and a mother for Abraham’s future generations. Because of this logic Abraham knows that God will make this happen. Abraham says confidently:

“He will send his angel before you so that you can get a wife for my son from there.”
