37:4ל״ז:ד׳
1 א

ולא יכלו דברו לשלום. מִתּוֹךְ גְּנוּתָם לָמַדְנוּ שִׁבְחָם, שֶׁלֹּא דִבְּרוּ אַחַת בַּפֶּה וְאַחַת בַּלֵּב:

ולא יכלו דברו לשלום AND THEY COULD NOT SPEAK PEACEABLY TO HIM — from what is stated to their discredit we may infer something to their credit: they did not speak one thing with their mouth having another thing quite different in their hearts (Genesis Rabbah 84:9).

2 ב

דברו. לְדַבֵּר עִמּוֹ:

דברו means TO SPEAK TO HIM.
