John Wesley on Leviticus 23:13

Two tenth deals - Or, parts, of an ephah, that is, two omers, whereas in other sacrifices of lambs there was but one tenth deal prescribed. The reason of which disproportion may be this, that one of the tenth deals was a necessary attendant upon the lamb, and the other was peculiar to this feast, and was an attendant upon that of the corn, and was offered with it in thanksgiving to God for the fruits of the earth.
