If you give to others, you will be given a full amount in return. It will be packed down, shaken together, and spilling over into your lap. The way you treat others is the way you will be treated.
If you forget to bring in a stack of harvested grain, don't go back in the field to get it. Leave it for the poor, including foreigners, orphans, and widows, and the LORD will make you successful in everything you do.
God is always fair. He will remember how you helped his people in the past and how you are still helping them. You belong to God, and he won't forget the love you have shown his people.
