'Seventh' in the Bible

On the seventh year, on the tenth day of the fifth month, men came from the elders of Israel to seek the LORD. They sat down in front of me.

On the seventh day of the first month of the eleventh year of our captivity, a message came to me from the LORD. It had this to say:

You are also to do this on the seventh day of the month, to make atonement for any person who wanders away or who sins through ignorance in order to make atonement for the Temple.

On the fifteenth day of the seventh month, during a seven day festival, the Regent Prince is to present these as daily sin offerings, burnt offerings, and grain offerings mixed with oil.'"
