'Tenth' in the Bible

speak ye unto all the company of Israel, saying, In the tenth of this month -- they take to them each man a lamb for the house of the fathers, a lamb for a house.

and the omer is a tenth of the ephah.

and a tenth deal of fine flour, mixed with beaten oil, a fourth part of a hin, and a libation, a fourth part of a hin, of wine, is for the one lamb.
