'Seventh' in the Bible

Now in the seventh year, in the fifth month, on the tenth of the month, certain of the elders of Israel came to inquire of the Lord, and sat before me.

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

Thus you shall do on the seventh day of the month for everyone who goes astray or is naive; so you shall make atonement for the house.

In the seventh month, on the fifteenth day of the month, at the feast, he shall provide like this, seven days for the sin offering, the burnt offering, the grain offering and the oil.”
