John Gill Commentary Ezekiel 4:11

"And thou shalt drink water by measure, the sixth part of a hin: from time to time shalt thou drink." — Ezekiel 4:11 (ASV)

You shall drink also water by measure Not wine, but water; and this not as much as he would, but a certain measure; which shows great want of it, and expresses a very distressed condition see (Lamentations 5:4) ; the sixth part of an hin ; a hin held twelve logs, or seventy two egg shells, or about three quarts of our measure; and the sixth part of one were two logs, or twelve egg shells, and about a pint of our measure; so that it was but a pint of water a day that the prophet was allowed, as a token of the great scarcity of it in the siege of Jerusalem: from time to time shall you drink : as before.
