Thus saith the Lord GOD: An evil, a singular evil, behold, it cometh.
Rashi on Ezekiel
An evil, a singular evil Heb. רָעָה אַחַתרָעָה, a total, special evil, worse than all evils; that is the destruction of the Temple.
Rashi on Ezekiel
behold it comes Heb. בָאָה. Its accent is on the ‘aleph.’ It is in the present tense.
