'Seventh' in the Bible

In the seventh year, in the fifth month, on the tenth of the month, some of the elders of Israel came to seek the Lord, and they sat down in front of me.

In the eleventh year, in the first month, on the seventh day of the month, the word of the Lord came to me:

This is what you must do on the seventh day of the month for anyone who sins inadvertently or through ignorance; so you will make atonement for the temple.

In the seventh month, on the fifteenth day of the month, at the feast, he will make the same provisions for the sin offering, burnt offering, and grain offering, and for the olive oil, for the seven days.
