'Eighth' in the Bible

And it happened on the eighth day that Moses called Aaron and his sons and the elders of Israel;

On the eighth day the flesh of the male child’s foreskin shall be circumcised.

“Now on the eighth day he shall take two male lambs without blemish, and a yearling ewe lamb without blemish, and three-tenths of an ephah of fine flour mixed with [olive] oil as a grain offering, and one log (about a pint) of oil;

He shall bring them on the eighth day for his [ceremonial] cleansing to the priest at the doorway of the Tent of Meeting, before the Lord.

On the eighth day he shall take two turtledoves or two young pigeons and come before the Lord to the doorway of the Tent of Meeting, and give them to the priest;

Then on the eighth day she shall take for herself two turtledoves or two young pigeons and bring them to the priest at the doorway of the Tent of Meeting;

“When a bull or a sheep or a goat is born, it shall remain for seven days with its mother; and after the eighth day it shall be accepted as an offering by fire to the Lord.

For seven days you shall present an offering by fire to the Lord. On the eighth day you shall have a holy convocation and present an offering by fire to the Lord. It is a festive assembly; you shall not do any laborious work [on that day].

‘On exactly the fifteenth day of the seventh month (nearly October), when you have gathered in the crops of the land, you shall celebrate the feast of the Lord for seven days, with a Sabbath rest on the first day and a Sabbath rest on the eighth day.

When you are sowing the eighth year, you can still eat old things from the crops, eating the old until the ninth year when its crop comes in.
