'Sacrifice' in the Bible

neither shall there fail to the priests the Levites a man before me to offer up burnt-offerings, and to burn oblations, and to do sacrifice continually.

For this is the day of the Lord Jehovah of hosts, a day of vengeance, that he may be avenged of his adversaries; and the sword shall devour, and it shall be sated and made drunk with their blood; for the Lord Jehovah of hosts hath a sacrifice in the north country, by the river Euphrates.
