Deuteronomy 12:31 "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."
God forbids human sacrifice, but the critics have a handful of instances where they think God had people violate this one:
Genesis 22:2 "And he said, Take now thy son, thine only son Isaac, whom thou lovest, and get thee into the land of Moriah; and offer him there for a burnt offering upon one of the mountains which I will tell thee of."
Since God's intent never was that Abraham complete the sacrifice, this is hardly contradictory. For more on this subject, see Glenn Miller's essay here
Exodus 22:29 "For thou shalt not delay to offer the first of thy ripe fruits, and of thy liquors; the firstborn of thy sons shalt thou give unto me."
This is not referring to sacrifice, but to service. No one sacrificed fruits and liquors on an altar.
Leviticus 27: 28-9 Notwithstanding no devoted thing, that a man shall devote unto the LORD of all that he hath, both of man and beast, and of the field of his possession, shall be sold or redeemed: every devoted thing is most holy unto the LORD. None devoted, which shall be devoted of men, shall be redeemed; but shall surely be put to death.
Is this human sacrifice? No, it is judicial execution. Those among men who are "devoted" (charam) are those who worship false gods (Exodus 22:19 He that sacrificeth unto any god, save unto the LORD only, he shall be utterly destroyed (charam.) or deceive others into doing so (Deut. 13:15).
Judges 11:30-39 "And Jephthah vowed a vow unto the Lord...

2 Samuel 21:8-14 "But the king [David] took the two sons of Rizpah . . . and the five sons of Michal . . . and he delivered them into the hands of the Gibeonites, and they hanged them in the hill before the Lord: and they fell all seven together, and were put to death in the days of harvest . . . And after that God was intreated for the land."
Do not leave out verses 10-14a, which tell us that God was intreated AFTER Saul's bones were reclaimed and buried. It had NOTHING to do with the sons of Rizpah, etc., or any human sacrifice.
Ezekiel 20:26 I let them become defiled through their gifts--the sacrifice of every firstborn --that I might fill them with horror so they would know that I am the LORD.
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.
Hebrews 10:10-12 " . . . we are sanctified through the offering of the body of Jesus Christ . . . But this man, after he had offered one sacrifice for sins forever, sat down on the right hand of God."
1 Corinthians 5:7 " . . . For even Christ our passover is sacrificed for us."
God offering the essence of Himself is human sacrifice? Human sacrifice always involved victims who were either a) deceived; b) unwilling. Jesus was neither. For more on this subject, see Glenn Miller's essay here.
