“At the end of every seven years you shall grant a release” (v1). The Mosaic Law commanded the Israelites to forgive debts and release bond-slaves every seven years, so that poverty would not have a chance to root itself among families for generations. God had released their ancestors from slavery (v15) and given them the Promised Land out of His own abundant mercy, and therefore, as His children, they were to show this same generosity to others.
“The Lord your God redeemed you” (v15). Because we deserve nothing yet have received forgiveness and blessing from God, we are called to treat those around us the same way.
