'Sacrifice' in the Bible

"Moreover they made a calf at that time, and offered a sacrifice to the idol and kept rejoicing in the gods which their own hands had made.

But even the sacrifice of my life I count as nothing, if only I may perfect my earthly course, and be faithful to the duty which the Lord Jesus has entrusted to me of proclaiming, as of supreme importance, the Good News of God's grace.

So Paul associated with the men; and the next day, having purified himself with them, he went into the Temple, giving every one to understand that the days of their purification were finished, and there he remained until the sacrifice for each of them was offered.
