'Tenth' in the Bible
then Yahweh your God will choose the place to have His name dwell. Bring there everything I command you: your burnt offerings, sacrifices, offerings of the tenth, personal contributions, and all your choice offerings you vow to the Lord.
Within your gates you may not eat: the tenth of your grain, new wine, or oil; the firstborn of your herd or flock; any of your vow offerings that you pledge; your freewill offerings; or your personal contributions.
“Each year you are to set aside a tenth of all the produce grown in your fields.
You are to eat a tenth of your grain, new wine, and oil, and the firstborn of your herd and flock, in the presence of Yahweh your God at the place where He chooses to have His name dwell, so that you will always learn to fear the Lord your God.
“At the end of every three years, bring a tenth of all your produce for that year and store it within your gates.
No one of illegitimate birth may enter the Lord’s assembly; none of his descendants, even to the tenth generation, may enter the Lord’s assembly.
No Ammonite or Moabite may enter the Lord’s assembly; none of their descendants, even to the tenth generation, may ever enter the Lord’s assembly.
“When you have finished paying all the tenth of your produce in the third year, the year of the tenth, you are to give it to the Levite, the foreigner, the fatherless, and the widow, so that they may eat in your towns and be satisfied.
