Ephraem the Syrian
Their sword shall be severed from before, meaning their offspring will be annihilated by their foes. There is fear within their dwellings. Their oppressors will inflict upon them the same dread that Cain experienced.
Without, the sword shall lay them waste, and terror within, both the young man and the virgin, the sucking child with the man in years.
מִחוּץ֙ תְּשַׁכֶּל־חֶ֔רֶב וּמֵחֲדָרִ֖ים אֵימָ֑ה גַּם־בָּחוּר֙ גַּם־בְּתוּלָ֔ה יוֹנֵ֖ק עִם־אִ֥ישׁ שֵׂיבָֽה׃
