Reference for Deuteronomy 16:20

Pursue justice! For the one who pursues justice and righteousness and gives charity and is quick with his compassion – in words and deeds - will find life and justice and honor. Do not fail to give the half Shekel once a year. Each week and month donate as much as you can to charity. Each day, before Prayers, give at least something, however small, to charity. When you can, tithe your assets and profits. Make sure you always are stocked with food and other provisions and resources at home with which you can readily help the needy, whether they are dead or alive, poor or rich.
