'Seventh' in the Bible

but the seventh day is a sabbath unto Jehovah thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, nor thy man-servant, nor thy maid-servant, nor thine ox, nor thine ass, nor any of thy cattle, nor thy stranger that is within thy gates; that thy man-servant and thy maid-servant may rest as well as thou.

Beware that there be not a base thought in thy heart, saying, The seventh year, the year of release, is at hand; and thine eye be evil against thy poor brother, and thou give him nought; and he cry unto Jehovah against thee, and it be sin unto thee.

If thy brother, a Hebrew man, or a Hebrew woman, be sold unto thee, and serve thee six years; then in the seventh year thou shalt let him go free from thee.

Six days thou shalt eat unleavened bread; and on the seventh day shall be a solemn assembly to Jehovah thy God; thou shalt do no work therein .
