'Free will' in the Bible

And if you offer a sacrifice of peace offerings to Jehovah, you shall offer it of your own free will.

And Kore the son of Imnah the Levite, the gatekeeper toward the east, was over the freewill offerings of God, to distribute the sacrifices of Jehovah and the most holy things.

And whoever remains in any place where he resides, let the men of his place help him with silver and with gold and with goods and with animals, besides the freewill offering for the house of God that is in Jerusalem.

And afterward they offered the continual burnt offering, both of the new moons and of all the set feasts of Jehovah that were set apart, and of everyone who willingly offered a freewill offering to Jehovah.

From me was made a decree that everyone of the people of Israel, and their priests and Levites in my kingdom, who desire of their own free will to go up to Jerusalem, go with you;

and all the silver and gold which you can find in all the province of Babylon, with the free will offering of the people and of the priests, offering willingly for the house of their God in Jerusalem.
