לֹֽא־יָס֨וּר ׀ מִנִּי־חֹ֗שֶׁךְ יֹֽ֭נַקְתּוֹ תְּיַבֵּ֣שׁ שַׁלְהָ֑בֶת וְ֝יָס֗וּר בְּר֣וּחַ פִּֽיו׃
他必不能脫離黑暗；火焰必使他的嫩枝枯乾，他必因祂口中的氣而消逝。
Rashi
by the breath of His mouth Of the Ruler of the world. This is an ellipsis, Others interpret this to mean: because of the breath of his mouth that was guilty of speaking lies.
