'Paying' in the Bible

You may buy food to eat and water to drink from them, paying with cash."'

"When you make a vow to the LORD your God, don't delay paying it, because the LORD your God will certainly demand payment from you, and then you will be guilty of sin.

“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.
