'One tenth' in the Bible
and there shall be one-tenth of an ephah of fine flour mixed with one-fourth of a hin of beaten oil, and one-fourth of a hin of wine for a drink offering with one lamb.
And if he is poor, and his hand is not reaching these things, then he hath taken one lamb -- a guilt-offering, for a wave-offering, to make atonement for him, and one-tenth deal of flour mixed with oil for a present, and a log of oil,
the man shall then bring his wife to the priest, and shall bring as an offering for her one-tenth of an ephah of barley meal; he shall not pour oil on it nor put frankincense on it, for it is a grain offering of jealousy, a grain offering of memorial, a reminder of iniquity.
The one who presents his offering shall present to the Lord a grain offering of one-tenth of an ephah of fine flour mixed with one-fourth of a hin of oil,
with one-tenth of an ephah of finely ground flour as a grain offering mixed with one quarter of a hin of pressed olive oil.
and one-tenth of an ephah of finely ground flour mixed with olive oil as a grain offering for each lamb, as a burnt offering for a pleasing aroma, an offering made by fire to the Lord.
For each of the seven lambs you are to offer one-tenth of an ephah,
and one-tenth deal for the one lamb, for the seven lambs;
The priest, the son of Aaron, shall be with the Levites when they receive tithes, and they shall bring one-tenth of the tithes up to the house of our God, to the chambers of the storehouse.
