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.
You refused to pay the people who worked in your fields, and now their unpaid wages are shouting out against you. The Lord All-Powerful has surely heard the cries of the workers who harvested your crops.
