אֲ֭נִי אָמַ֣רְתִּי בְחָפְזִ֑י כָּֽל־הָאָדָ֥ם כֹּזֵֽב׃
[Pourtant] j’avais dit dans ma précipitation: "Tout dans l’homme est trompeur!"
Rashi
that you failed Heb. תְּכַזֵּבִי, that you ceased to worship Me and you betrayed Me. Comp. (infra 58:11) “Whose water shall not fail (יְכַזְּבוּ).” Comp. also (Psalms 116:11) “Every man is a traitor (כֹּזֵב).” Falajjnc in O.F., to fail. Likewise, every expression of כָּזָב means one upon whom people rely, and he fails and betrays them.
