'Free will' in the Bible

and at his side, Amasiah the son of Zicri, who had made a freewill offering to Yahweh, and with him [were] two hundred thousand mighty armed warriors.

Now Kore the son of Imlah, the Levite, the gatekeeper of the east gate [was] over the freewill offerings of God, to give offerings to Yahweh and the most holy things.

And his officials contributed a freewill offering to the people, to the priests, and to the Levites. Hilkiah, Zechariah, and Jehiel, commanders of the house of God, gave to the priests two thousand six hundred Passover [lambs] and three hundred bulls.
