John Gill Commentary Ezekiel 7:5

"Thus saith the Lord Jehovah: An evil, an only evil; behold, it cometh." — Ezekiel 7:5 (ASV)

Thus says the Lord God
Here should be a stop, a colon, requiring attention to what follows, it being something awful and terrible: an evil, an only evil, behold, it comes ;
meaning the destruction of the city and temple; which, though but one, was such an one as was never known before nor was there any like it. The Targum is, ``evil after evil, lo, it comes;'' one evil after another; when one evil is gone, another comes, as in (Ezekiel 7:26) . The Syriac version is, "behold, evil for evil comes"; the evil of punishment for the evil of sin.
