דַּלְתֵ֣י פָ֭נָיו מִ֣י פִתֵּ֑חַ סְבִיב֖וֹת שִׁנָּ֣יו אֵימָֽה׃
Wer hat je die Türen seines Antlitzes [seinen Rachen] geöffnet? Um sein Gebiss ist Schrecken.
Rashi on Job
the doors of his face They are the lips when he closes his mouth; who can open them?
Rashi on Job
Around his teeth is terror That because of his fright and his terror, no creature can approach his teeth.
