וּלְשֽׁוֹנְךָ֙ אַדְבִּ֣יק אֶל־חִכֶּ֔ךָ וְנֶֽאֱלַ֔מְתָּ וְלֹא־תִֽהְיֶ֥ה לָהֶ֖ם לְאִ֣ישׁ מוֹכִ֑יחַ כִּ֛י בֵּ֥ית מְרִ֖י הֵֽמָּה׃
Et j’attacherai ta langue à ton palais, tu deviendras muet, et tu ne leur seras pas un sermonneur, car ils sont une maison de rébellion.
Rashi
and He opened my mouth as He says in the beginning of the Book (3:26): “and you shall become mute, and you shall not be a reprover to them.” Afterward, He said to him (24:25ff.): “on the day I take from them their strength, etc., the fugitive will come to you, etc., on that day, your mouth will be opened with the fugitive, and you will speak and no longer be mute.”
Rashi
and you will speak and no longer be mute Because I said to you (3:26): “and you shall become mute, and you shall not be, etc.” From now on, they will see that your words are true, and you will no longer be mute from prophesying to them.
