Another instance in which posterity is recognized in covenant obligation is found in Joshua 9:15. This covenant was made between the children of Israel and the Gibeonites. Between four and five hundred years after that time, the children of Israel are visited with a very severe famine, in the days of David. 2 Sam. 21:1. And it is expressly declared by the Lord that, 'It is for Saul, and for his bloody house, because he slew the Gibeonites.' And at the same time, v. 2, that very covenant is recognized, and the breach of it is stated, as being the formal reason of the divine displeasure. Now, had it not been for this covenant, the extirpation of the Gibeonites would not have been imputed to Israel as a thing criminal; for they were comprehended in Canaanitish nations, which God had commanded them to root out. - William L.
