Exodus 16:16

An omer - i. e. the tenth part of an Ephah, see Exodus 16:36. The exact quantity cannot be determined, since the measures varied at different times. Josephus makes the omer equal to six half-pints. The ephah was an Egyptian measure, supposed to be about a bushel or one-third of a hin. The word omer, in this sense, occurs in no other passage. It was probably not used at a later period, belonging, like many other words, to the time of Moses. It is found in Old Egyptian. See Leviticus 19:36.
