Genesis 24:4
"But you will go to my country and to my relatives, and take a wife for my son Isaac."
Abraham's desire to get a suitable wife for his son is commendable. He was well aware that if Isaac married a Canaanite women, it might prevent the spread of the true religion; therefore he binds his most trusty servant by a solemn oath not to take a wife for his son from the daughters of Canaan, but from his own kindred, among whom the knowledge of the true God was best preserved. Others had different rays of the light of truth, but Abraham's family alone had The truth; and to the descendants of this family were the promises made.
By desire of his master he (Eliezer) went out on this journey; and as he acknowledged God in all his ways, the Lord directed all his steps.
The Truth
“In all your ways acknowledge Him, And He shall direct your paths.” (Proverbs 3:6)
