'Seventh' in the Bible

but the seventh day is a Sabbath [a day of rest dedicated] to the Lord your God; on that day you shall not do any work, you or your son or your daughter or your male servant or your female servant or your ox or your donkey or any of your livestock or the stranger who stays inside your [city] gates, so that your male servant and your female servant may rest as well as you.

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].

For six days you shall eat unleavened bread, and on the seventh day there shall be a celebration to the Lord your God; so you shall do no work [on that day].
