'Seventh Year' in the Bible

Beware that there is no base thought in your heart, saying, ‘The seventh year, the year of remission, is near,’ and your eye is hostile toward your poor brother, and you give him nothing; then he may cry to the Lord against you, and it will be a sin in you.

“If your kinsman, a Hebrew man or woman, is sold to you, then he shall serve you six years, but in the seventh year you shall set him free.
