'Seventh Year' in the Bible

Beware that there is no wicked thought in your heart, saying, ‘The seventh year, the year of release (remission, pardon), is approaching,’ and your eye is hostile (unsympathetic) toward your poor brother, and you give him nothing [since he would not have to repay you]; for he may cry out to the Lord against you, and it will become a sin for you.

“If your fellow Israelite, a Hebrew man or woman, is sold to you, and serves you for six years, then in the seventh year you shall set him free [from your service].
