'Seventh Year' in the Bible

Be careful that there isn’t this wicked thought in your heart, ‘The seventh year, the year of canceling debts, is near,’ and you are stingy toward your poor brother and give him nothing. He will cry out to the Lord against you, and you will be guilty.

“If your fellow Hebrew, a man or woman, is sold to you and serves you six years, you must set him free in the seventh year.
