Charles Ellicott Commentary Ezekiel 45:12

"And the shekel shall be twenty gerahs; twenty shekels, five and twenty shekels, fifteen shekels, shall be your maneh." — Ezekiel 45:12 (ASV)

The shekel. The first part of this verse is merely a restatement of the old law (Exodus 30:13; Leviticus 27:25; Numbers 3:47) that the shekel should be of the value of twenty gerahs, or of the estimated weight of 220 grains; but the latter part of the verse is extremely obscure. The maneh is mentioned elsewhere only in 1 Kings 10:17; Ezra 2:69; Nehemiah 7:71, and is translated in our version pound. Its actual value is unknown. If the text as it stands is correct, it is possible that in Ezekiel’s time three different manehs were in use, of the values respectively assigned to them; but of this there is no other evidence.
