it may be a bit of a stretch to say that Abraham was talking about jesus when he said those words- here's the passage:For example, when Abraham was asked to sacrifice Isaac, Abraham said, "God would provide His own sacrifice" before it was even declared to Abraham by God. This was recounted by Moses roughly 1,500 years before God actually provided His own sacrifice. That indicates to be that God "knew" what He would be doing later.
I understand and agree that this whole episode pre-figures the death and sacrifice of Jesus, but that is different from saying Abraham was predicting this when he said that God would provide a lamb for the burnt offering. i think abraham was talking about what was directly in front of him, namely the possibility that he would have to kill his son and his hope(faith) that he would not have to do so.But Isaac spoke to Abraham his father and said, “My father!”
And he said, “Here I am, my son.”
Then he said, “Look, the fire and the wood, but where is the lamb for a burnt offering?” And Abraham said, “My son, God will provide for Himself the lamb for a burnt offering.” So the two of them went together.
