Like a young plant or a root that sprouts in dry ground, the servant grew up obeying the LORD. He wasn't some handsome king. Nothing about the way he looked made him attractive to us.
When Moses asked around and learned that the ram for the sin sacrifice had already been burned on the altar, he became angry with Eleazar and Ithamar and said,
Tell the people of Israel that they must offer sacrifices as well. They must offer a goat as a sacrifice for sin, and a bull and a ram as a sacrifice to please the LORD. The bull and the ram must be a year old and have nothing wrong with them.
And if the animal is a full-grown ram, you must offer four pounds of flour mixed with one and a half quarts of olive oil. One and a half quarts of wine must also be poured on the altar. The smell of this smoke is pleasing to me.
The Law of Moses cannot do this, because our selfish desires make the Law weak. But God set you free when he sent his own Son to be like us sinners and to be a sacrifice for our sin. God used Christ's body to condemn sin.
