Therefore Abraham wished to acquire the Cave of Machpelah from the children of Heth, the inhabitants of the city of Jebus. They said to him. "We know that in time to come God will give these lands unto thy seed, and now do thou swear a covenant with us that Israel shall not wrest the city of Jebus from its inhabitants without their consent." Abraham agreed to the condition, and he acquired the field from Ephron, in whose possession it lay.
This happened the very day on which Ephron had been made the chief of the children of Heth, and he had been raised to the position so that Abraham might not have to have dealings with a man of low rank. It was of advantage to Abraham, too, for Ephron at first refused to sell his field, and only the threat of the children of Heth to depose him from his office, unless he fulfilled the desire of Abraham, could induce him to change his disposition.
