'Seventh' in the Bible

And it came to pass in the seventh year, in the fifth month, the tenth of the month, that certain of the elders of Israel came to inquire of Jehovah, and they sat before me.

And it came to pass in the eleventh year, in the first month, on the seventh of the month, the word of Jehovah came unto me, saying,

So thou shalt do also on the seventh of the month for every one that erreth, and for the simple; and ye shall make atonement for the house.

In the seventh month, on the fifteenth day of the month, at the feast, shall he do the like seven days, according to the sin-offering, according to the burnt-offering, and according to the oblation, and according to the oil.
