'Seventh' in the Bible

but the seventh day is a Sabbath to the Lord your God. You must not do any work—you, your son or daughter, your male or female slave, your ox or donkey, any of your livestock, or the foreigner who lives within your gates, so that your male and female slaves may rest as you do.

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.

You must eat unleavened bread for six days. On the seventh day there is to be a solemn assembly to the Lord your God, and you must not do any work.
