But in the fourth generation they shall come here again: for the iniquity of the Amorites is not yet complete.
All Commentaries on Genesis 15:16 Go To Genesis 15
Didymus the Blind
AD 398
What is clearly stated in the text can be expounded as follows. When the sun was already near setting, a flame emerged, and there appeared a smoking oven and fiery torches “that passed between the two parts of the divided animals,” burning and lighting up the place, to allow the patriarch to see what was happening and to reveal in a more divine manner the mysteries to be searched out. It should be noted that a fire did not appear only after the covenant had been made, but the gift of the law through Moses took place itself in the midst of a fire. Fire could be seen, and, without being able to see the one who was speaking, the giving of the commandments could be heard. What is suggested here is perhaps something like this. As the law contains rewards and punishments, it was given in the midst of fire to indicate that it brings burning to some and illumination to others. In fact, fire has a twofold power: it illuminates, and at the same time it burns. The gift of the law, then, burns those who abandon it and enlightens those who observe it. So too here, torches and smoke appeared; now smoke is the result and as it were the consequence of a fire that has been lit. Moreover, a flame had appeared first. We conclude, then, that one who is defining what is to be done and what is not to be done in a matter this difficult requires the light of God and also fear, symbolized by the furnace, so as to accomplish everything in accordance with right reason.
