Charles Ellicott Commentary Deuteronomy 15:1

"At the end of every seven years thou shalt make a release." — Deuteronomy 15:1 (ASV)

At the end of every seven years you shall make a release. —The Law in this place is an extension of that which we find in Exodus 21:2 and following, and Leviticus 25:3 and following. There was not only to be a manumission of Hebrew slaves and a Sabbath for the land in the seventh year, but also a release of debts, of which all the Israelites must have the benefit.
