Genesis 8:20

8:20 Noah built an altar to the Lord. He then took some of every kind of clean animal and clean bird and offered burnt offerings on the altar. 1 

Genesis 22:8

22:8 “God will provide 2  for himself the lamb for the burnt offering, my son,” Abraham replied. The two of them continued on together.

1 sn Offered burnt offerings on the altar. F. D. Maurice includes a chapter on the sacrifice of Noah in The Doctrine of Sacrifice. The whole burnt offering, according to Leviticus 1, represented the worshiper’s complete surrender and dedication to the Lord. After the flood Noah could see that God was not only a God of wrath, but a God of redemption and restoration. The one who escaped the catastrophe could best express his gratitude and submission through sacrificial worship, acknowledging God as the sovereign of the universe.

2 tn Heb “will see for himself.” The construction means “to look out for; to see to it; to provide.”

sn God will provide is the central theme of the passage and the turning point in the story. Note Paul’s allusion to the story in Rom 8:32 (“how shall he not freely give us all things?”) as well as H. J. Schoeps, “The Sacrifice of Isaac in Paul’s Theology,” JBL 65 (1946): 385-92.
