'Offering' in the Bible

So it came about in the course of time that Cain brought an offering to the Lord of the fruit of the ground.

Abel, on his part also brought of the firstlings of his flock and of their fat portions. And the Lord had regard for Abel and for his offering;

but for Cain and for his offering He had no regard. So Cain became very angry and his countenance fell.

He said, “Take now your son, your only son, whom you love, Isaac, and go to the land of Moriah, and offer him there as a burnt offering on one of the mountains of which I will tell you.”

So Abraham rose early in the morning and saddled his donkey, and took two of his young men with him and Isaac his son; and he split wood for the burnt offering, and arose and went to the place of which God had told him.

Abraham took the wood of the burnt offering and laid it on Isaac his son, and he took in his hand the fire and the knife. So the two of them walked on together.

Isaac spoke to Abraham his father and said, “My father!” And he said, “Here I am, my son.” And he said, “Behold, the fire and the wood, but where is the lamb for the burnt offering?”

Abraham said, “God will provide for Himself the lamb for the burnt offering, my son.” So the two of them walked on together.

Then Abraham raised his eyes and looked, and behold, behind him a ram caught in the thicket by his horns; and Abraham went and took the ram and offered him up for a burnt offering in the place of his son.
