I.e., the tenth part of an ephah (as in the R.V.), equal to an omer or six pints. The recovered leper, to complete his purification, was required to bring a trespass, a sin, and a burnt offering, and to present a meal offering, a tenth deal or an omer of flour for each, with oil to make it into bread or cakes (Lev. 14:10, 21; comp. Ex. 16:36; 29:40).
