Genesis 21-23

Moses didn't say how old Isaac was when his father heard the command to sacrifice him. He was old enough to carry a load of wood and he was probably accustomed to obeying his father's command. When Abraham commanded Isaac to put his hands behind his back there may have been little concern. As his hands were tied together he surely was wondering what was happening. But there had to be fear in his eyes as he saw old Abraham raise the knife. Just three days earlier those arms had cut up the wood the Isaac carried. There could be no question Abraham had the strength to hold down his son and cut his throat. But the the angel spoke. I wonder if Isaac heard the conversatiopn. I think he did. I'm convinced that he heard the compassion of heaven and the devotion of his father. And the promise of many children through the boy lying on the altar. Through that conversation Isaac received a promise for his life.
