Hebrews 11:17

offered up--literally, "hath offered up," as if the work and its praise were yet enduring [ALFORD]. As far as His intention was concerned, he did sacrifice Isaac; and in actual fact "he offered him," as far as the presentation of him on the altar as an offering to God is concerned. tried--Greek, "tempted," as in Gen 22:1. Put to the proof of his faith. Not that God "tempts" to sin, but God "tempts" in the sense of proving or trying (Jam 1:13-15). and--and so. he that had received--rather as Greek, "accepted," that is, welcomed and embraced by faith, not merely "had the promises," as in Heb 7:6. This added to the difficulty in the way of his faith, that it was in Isaac's posterity the promises were to be fulfilled; how then could they be fulfilled if Isaac were sacrificed? offered up--rather as Greek, "was offering up"; he was in the act of offering. his only-begotten son--Compare Gen 22:2, "Take now thy son, thine only son." EUSEBIUS [The Preparation of the Gospel, 1.10, and 4.16], has preserved a fragment of a Greek translation of Sanchoniatho, which mentions a mystical sacrifice of the Phœnicians, wherein a prince in royal robes was the offerer, and his only son was to be the victim: this evidently was a tradition derived from Abraham's offering, and handed down through Esau or Edom, Isaac's son.
