'Sacrifice' in the Bible

neither shall the priests the Levites want a man before me to offer burnt-offerings, and to burn meal-offerings, and to do sacrifice continually.

For that day is a day of the Lord, Jehovah of hosts, a day of vengeance, that he may avenge him of his adversaries: and the sword shall devour and be satiate, and shall drink its fill of their blood; for the Lord, Jehovah of hosts, hath a sacrifice in the north country by the river Euphrates.
