Abraham call on his elder servant to find a wife for his son. He has him taken oath and promise him that he’ll bring back a wife but not bring Isaac out there to marry.

I did forget to mention one important aspect, which is the fact that Abraham tells his servant that he will send a messenger (angel) ahead of him and he’ll take a wife for his son.

This is pure confidence that Abraham has that God is going to help us servant and lead him to finding a wife who will come back with him that he can bring back for his son! He believes God is going ahead of the servant to prepare and make that message clear. This way the wife and her family will have a soft heart that’s ready when the proposal from the servant comes!
