Deuteronomy 12:31 forbids human sacrifice: 'Thou shalt not do so unto the Lord thy God: for every abomination to the Lord, which he hateth, have they done unto their gods; for even their sons and their daughters they have burnt in the fire to their gods.'

However, critics point to instances they claim violate this command.

Genesis 22:2: 'Take now thy son, thine only son Isaac... and offer him there for a burnt offering...'
Since God's intent never was that Abraham complete the sacrifice, this is not a contradiction. God was testing Abraham's faith, not demanding human sacrifice.

Exodus 22:29: '...the firstborn of thy sons shalt thou give unto me.'
This is not referring to sacrifice, but to service to God. No one sacrificed fruits and liquors on an altar.

Leviticus 27:28-29: '...every devoted thing is most holy unto the LORD... but shall surely be put to death.'
This is judicial execution, not human sacrifice. Those among men who are 'devoted' (charam) are those who worship false gods or deceive others into doing so.

2 Samuel 21:8-14: '...and he delivered them into the hands of the Gibeonites, and they hanged them in the hill before the Lord...'
Verses 10-14 tell us that God was intreated AFTER Saul's bones were reclaimed and buried. It had NOTHING to do with the sons of Rizpah, or any human sacrifice.

Ezekiel 20:26: 'I let them become defiled through their gifts--the sacrifice of every firstborn...'
This is not a case of endorsing human sacrifice, but a case of God giving rebellious peoples what they want and deserve by giving them freedom to pursue their own destructive desires.

Hebrews 10:10-12 / 1 Corinthians 5:7: '...we are sanctified through the offering of the body of Jesus Christ...'
Is God offering the essence of Himself as a human sacrifice? Human sacrifice always involved victims who were either a) deceived; or b) unwilling. Jesus was neither.
