'Tenth' in the Bible

Speak to all the community of Israel, saying, 'On the tenth of this month, they will each take for themselves {a lamb for the family}, a lamb for the household.

(And an omer [is] a tenth of an ephah.)

And a tenth of finely milled flour mixed with a fourth of a hin of beaten oil, and a fourth of a hin of wine as a libation with the first lamb.
