tithe; 10% of ones income.
question; If you are unemployed, what is your income?
Biblically speaking, few Hebrews tithed. A tithe was never money. It was what your grew or raised. If you didn’t grow anything you didn’t tithe.
Tithe, is 10% of your increase. Your increase is your profit. So 10% would be after your bills to keep yourself warm, fed and able to go to work. If they ask for anything more they are greedy.
