Commentary for Job 2:13

וַיֵּשְׁב֤וּ אִתּוֹ֙ לָאָ֔רֶץ שִׁבְעַ֥ת יָמִ֖ים וְשִׁבְעַ֣ת לֵיל֑וֹת וְאֵין־דֹּבֵ֤ר אֵלָיו֙ דָּבָ֔ר כִּ֣י רָא֔וּ כִּֽי־גָדַ֥ל הַכְּאֵ֖ב מְאֹֽד׃

So they sat down with him upon the ground seven days and seven nights, and none spoke a word unto him; for they saw that his grief was very great.
