'Free will' in the Bible

and bring in thither your ascending-offerings and your sacrifices, and your tithes, and the heave-offering of your hand, - and your vow-offerings and your freewill-offerings, and the firstlings of your herd and of your flock;

Thou mayest not eat within thy gates, the tithe of thy corn or of thy new wine or of thine oil, or the firstlings of thy herd, or of thy flock, - nor any of thy vow-offerings which thou shalt vow, nor thy freewill, offerings, nor the heave-offering of thy hand;

So shalt thou keep the festival of weeks unto Yahweh thy God, in the measure of the freewill offering of thy hand which thou shalt give, - as Yahweh thy God shall bless thee.

That which goeth forth out of thy lips, thou must observe and do, - according as thou didst vow unto Yahweh thy God the free-will, offering of which thou didst speak with thy mouth.
