'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, Yahweh of Armies, 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, Yahweh of Armies, has a sacrifice in the north country by the river Euphrates.
