John Gill Commentary Ezekiel 45:11

"The ephah and the bath shall be of one measure, that the bath may contain the tenth part of a homer, and the ephah the tenth part of a homer: the measure thereof shall be after the homer." — Ezekiel 45:11 (ASV)

The ephah and the bath shall be of one measure
The one held as much of dry things as the other of liquor; which, according to Bishop Cumberland, were seven wine gallons, four pints, and a little more:

that the bath may contain the tenth part of an homer, and the ephah the
tenth part of an homer ;
this "homer" must be carefully distinguished from another measure, called "omer", written without an "h", which was but the tenth part of an "ephah", (Exodus 16:36):

the measure thereof shall be after the homer :
"as the homer was", so should the ephah and bath be, just the tenth part of it.
