'Sacrifice' in the Bible

and it cometh to pass, in God's helping the Levites bearing the ark of the covenant of Jehovah, that they sacrifice seven bullocks and seven rams.

And they sacrifice to Jehovah sacrifices, and cause to ascend burnt-offerings to Jehovah on the morrow of that day, bullocks a thousand, rams a thousand, lambs a thousand, and their oblations, even sacrifices in abundance, for all Israel.
