לֹֽא־יָס֨וּר ׀ מִנִּי־חֹ֗שֶׁךְ יֹֽ֭נַקְתּוֹ תְּיַבֵּ֣שׁ שַׁלְהָ֑בֶת וְ֝יָס֗וּר בְּר֣וּחַ פִּֽיו׃
He shall not depart out of darkness; The flame shall dry up his branches, And by the breath of His mouth shall he go away.
Rashi on Job
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.
