The Greek adjective ekdotos means delivered over, surrendered, or handed up — one who has been given into another's hands. It comes from ekdidōmi (to give out, deliver over) and appears in the New Testament in the context of Jesus being handed over to His enemies.
Ekdotos appears in Acts 2:23 in Peter's Pentecost sermon: Jesus was 'delivered up according to the definite plan and foreknowledge of God.' The word captures the divine intentionality behind the crucifixion — Jesus was not a hapless victim but one deliberately 'given over' in accordance with the eternal counsel of God. This is the theology of the atonement: God delivered His own Son into the hands of sinful men to accomplish redemption. The cross was not a tragedy derailing God's plan but the very execution of it.
