'Seventh' in the Bible

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

And it came to pass in the eleventh year, in the first month, in the seventh day of the month, that the word of the LORD came unto me, saying,

And so thou shalt do the seventh day of the month for every one that erreth, and for him that is simple: so shall ye reconcile the house.

In the seventh month, in the fifteenth day of the month, shall he do the like in the feast of the seven days, according to the sin offering, according to the burnt offering, and according to the meat offering, and according to the oil.
