Offerings » Free-will » Obligatory when signified in a vow
Then you shall celebrate the Feast of Weeks to the Lord your God with a tribute of a freewill offering of your hand, which you shall give just as the Lord your God blesses you;
You shall be careful to perform what goes out from your lips, just as you have voluntarily vowed to the Lord your God, what you have promised.
