“For I know him, that he will command his children and his household after him, and they shall keep the way of the LORD, to do justice and judgment; that the LORD may bring upon Abraham that which he hath spoken of him.” Genesis 18:19
There are three things very remarkable in this verse.
1. That Abraham used parental authority in governing his family: “For I know him, that he will command his children and his household after him.” He did not think it enough to pray for them, or to teach them, but he used the authority which God had given him—he commanded them.
2. That he cared for his servants as well as his children. In Genesis 14:14, we learn that Abraham had three hundred and eighteen servants born in his house. He lived after the manner of patriarchal times; as the Arabs of the wilderness do to this day. His family was very large, and yet he did not say, “They are none of mine.” He commanded his children and his household.
3. His success: “they shall keep the way of the LORD.” It is often said that the children of good men turn out ill. Well, here is a good man, and a good man doing his duty by his children—and here is the result. His son Isaac was probably a child of God from his earliest years. There is every mark of it in his life. And what a delightful specimen of a believing, prayerful servant was Eliezer! (Gen. 24.)
