Answer:
lamb, fulfillment
Explanation:
The sacrificing of a lamb was carried out multiple times throughout the old testament as a type of absolving of sins. This is seen most clearly in the plague that the Israelites evaded by placing an x made of blood above their doors.
For the second, fulfillment is the only one that makes sense in the sentence because in order for it to be a sacrifice it had to be a decision and this is shown in the garden scene, because even though it wasn't what he wanted he still followed through with God's will.
