New Defender's Study Bible Notes
22:5 worship. The word for “worship” (Hebrew shachah) means simply “bow down”–that is, submit to God’s will. This is what Christ did, perfectly, on the cross.
22:5 come again. Note Abraham’s great faith. At a time when no one had ever come back from the dead, Abraham so strongly believed that God would keep His word concerning Isaac that he believed God would raise him from the dead after he had obeyed God in slaying him (Hebrews 11:17-19).
