3 ¶ And Abraham rose up early in the morning, and saddled his ass, and took two of his young men with him, and Isaac his son, and clave the wood for the burnt offering, and rose up, and went unto the place of which God had told him. 4 Then on the third day Abraham lifted up his eyes, and saw the place afar off. 5 And Abraham said unto his young men, Abide ye here with the ass; and I and the lad will go yonder and worship, and come again to you. 6 And Abraham took the wood of the burnt offering, and laid it upon Isaac his son; and he took the fire in his hand, and a knife; and they went both of them together. 7 And Isaac spake unto Abraham his father, and said, My father: and he said, Here am I, my son. And he said, Behold the fire and the wood: but where is the lamb for a burnt offering? 8 And Abraham said, My son, God will provide himself a lamb for a burnt offering: so they went both of them together. 9 And they came to the place which God had told him of; and Abraham built an altar there, and laid the wood in order, and bound Isaac his son, and laid him on the altar upon the wood. 10 And Abraham stretched forth his hand, and took the knife to slay his son.
11 ¶ And the angel of the LORD called unto him out of heaven, and said, Abraham, Abraham: and he said, Here am I. 12 And he said, Lay not thine hand upon the lad, neither do thou any thing unto him: for now I know that thou fearest God, seeing thou hast not withheld thy son, thine only son from me. 13 And Abraham lifted up his eyes, and looked, and behold behind him a ram caught in a thicket by his horns: and Abraham went and took the ram, and offered him up for a burnt offering in the stead of his son. 14 And Abraham called the name of that place Jehovahjireh: as it is said to this day, In the mount of the LORD it shall be seen.
Without questioning Abraham proceeds toward his obedience to God’s seemingly horrific command. For we know that human sacrifice is forbidden by God as an act of worship.
Jeremiah 32:35 And they built the high places of Baal, which are in the valley of the son of Hinnom, to cause their sons and their daughters to pass through the fire unto Molech; which I commanded them not, neither came it into my mind, that they should do this abomination, to cause Judah to sin.
Mount Moriah is what we know today as the Temple Mount.
2Chronicles 3:1 Then Solomon began to build the house of the LORD at Jerusalem in mount Moriah, where the LORD appeared unto David his father, in the place that David had prepared in the threshingfloor of Ornan the Jebusite.
The third day represents to us the resurrection of Christ after three days.
Luke 24:46 And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day:
This resurrection is a theme mentioned in several places in prophetic verses in the Old Testament.
Hosea 6:2 After two days will he revive us: in the third day he will raise us up, and we shall live in his sight.
Isaac as a type of Christ. Verse 8 shows Abraham speaking a prophecy of Christ, the Lamb of God (John 1:29, 36), as it is a ram that is provided for this sacrifice as a ram is the sacrifice of Aaron and his son’s consecration as God’s priests in Exodus 29. Isaac is being set apart for God’s purpose and we are being given a glimpse of Christ’s sacrifice and resurrection.
…God will provide himself a lamb for a burnt offering…
Notice here that to stop him, God, as the angel of the Lord, the appearance of God, which appearance is Christ as we have seen, calls Abraham out of heaven. Notice the similar scene with Hagar in preceding passages.
