'Free will' in the Bible

Kore the son of Imnah the Levite, keeper of the East Gate, was in charge of the voluntary offerings to God, to apportion the contributions for the Lord and the most holy things.

His officers also contributed a voluntary offering to the people, the priests and the Levites. Hilkiah, Zechariah, and Jehiel, the officials of the house of God, gave to the priests for the Passover offerings 2,600 from the flocks [of lambs and young goats], and 300 bulls.
