'Seventh' in the Bible

but the seventh day is the sabbath of Jehovah thy God: thou shalt not do any work, thou, nor thy son, nor thy daughter, nor thy bondman, nor thy handmaid, nor thine ox, nor thine ass, nor any of thy cattle, nor thy sojourner that is within thy gates; that thy bondman and thy handmaid may rest as well as thou.

Beware that there be not a wicked 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 givest him nought; and he cry against thee to Jehovah, and it be sin in thee.

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

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