'Sacrifice' in the Bible

For your servant made a vow while I lived at Geshur in Aram (Syria), ‘If the Lord will in fact bring me back to Jerusalem, then I will serve the Lord [by offering a sacrifice of thanksgiving].’”

Araunah said to David, “Let my lord the king take and offer up whatever seems good to him. Look, here are oxen for the burnt offering, and threshing sledges and the yokes of the oxen for the wood.
