Holokautōma (ὁλοκαύτωμα) means whole burnt offering — a sacrifice entirely consumed by fire, nothing reserved. From holos (whole) + kautos (burned). The most complete OT sacrifice, representing total consecration.
Hebrews 10:6,8 quotes Psalm 40: God 'did not desire' mere ritual sacrifices but a body prepared for Christ. Mark 12:33: loving God and neighbor 'is more important than all burnt offerings.' The OT sacrificial system always pointed beyond itself. Jesus is the ultimate whole burnt offering: completely given, nothing held back, totally consumed by divine judgment on our behalf. Romans 12:1 calls us to respond: 'offer your bodies as a living sacrifice.'
