The host used this text to answer Ezekiel 18 by arguing that, within Torah, blood is God's appointed means of atonement, so Jesus' sacrificial death is scripturally coherent.

Leviticus 17:10-11
bible
10 "'Any man of the house of Israel, or of the strangers who live as foreigners among them, who eats any kind of blood, I will set my face against that soul who eats blood, and will cut him off from among his people. 11 For the life of the flesh is in the blood; and I have given it to you on the altar to make atonement for your souls: for it is the blood that makes atonement by reason of the life.
Used to object that consuming blood is forbidden in Torah, so Eucharistic language about drinking Messiah's blood would be unlawful unless superseded by divine authority.
Read to support the claim that blood is given on the altar to make atonement, so sacrificial blood is central to forgiveness/atonement in the Old Testament.
