John Gill Commentary Ezekiel 32:17

"It came to pass also in the twelfth year, in the fifteenth [day] of the month, that the word of Jehovah came unto me, saying," — Ezekiel 32:17 (ASV)

It came to pass also the twelfth year
Another prophecy of the like kind was delivered out the same year as before: in the fifteenth day of the month ;
of the twelfth month, the month Adar, which is not here expressed, because mentioned before, (Ezekiel 32:1) , it was about a fortnight after the other prophecy. The Septuagint and Arabic versions read it, ``it came to pass in the twelfth year, the first month, the fifteenth day of the month;'' according to which this prophecy was before the other, which is not to be supposed.
