At the close of chapter xxvi. we read: "And Esau was forty years old when he took to wife Judith the daughter of Beeri the Hittite, and Bashemath the daughter of Elon the Hittite: which were a grief of mind to Isaac and to Rebekah."
This has much for us in the way of admonition; but to use it aright, I must look to things connected with it, or like it, in the earlier history of Abraham, and then in the future histories of Jacob and his son Judah.
The command to the nation of Israel at the very beginning was to keep the way of the Lord very particularly as to _marriage_. They were by no means either to give their daughters to the sons of the Canaanites, or take the Canaanites’ daughters for their sons. Deut. vii. 3. If they did so, it would be on the pain of being no longer owned of the Lord. Josh. xxiii. According to this, the apostate days of Solomon are marked by disobedience to this very thing (1 Kings xi.); and afterwards, no real recovery to God could be admitted, without a return to the observance of this principle in their marriages. Ezra x.; Neh. x.
Obedience, therefore, in this thing was a peculiar test of the state of the nation. And it is thus that I look at it in this earliest book of Genesis. For though divine law was not then published, divine principles were then understood. It may be regarded as the witness of the state of _family_ religion then, as it was of the state of _national_ religion afterwards.
Abraham, in this matter, eminently keeps "the way of the Lord;" and so Eliezer, one of his "household;" and so our Isaac, one of his "children." For Abraham sends a special embassy into a distant land, in order to get a wife "in the Lord" for his son--Eliezer goes on that embassy with a ready mind--and Isaac in patience waits for the fruit of it, not seeking any alliance with the nearer people; and, though sad and solitary, keeps himself for the Lord’s appointed helpmeet. Like Adam, he waited for a helpmeet from the Lord’s own hand, though it cost him patience and sore solitude. This his meditation in the field at eventide shows. He endured. He might have got a daughter of Canaan; but he endured. He will rather suffer the sickening of his heart from the deferring of his hope, than not marry "in the Lord," or take him a wife of any that he may choose. And all this was very beautiful in this first generation of this elect family. The father, the servant, and the child, each in his way, witnesses how Abraham had ordered his house according to God, teaching his children and his household the way of the Lord. See chap. xviii. 19.
