'Free will' in the Bible

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.

And I said to them, You are holy to Jehovah, and the vessels are holy. And the silver and the gold are a free-will offering to Jehovah, the God of your fathers.
