וּלְשֽׁוֹנְךָ֙ אַדְבִּ֣יק אֶל־חִכֶּ֔ךָ וְנֶֽאֱלַ֔מְתָּ וְלֹא־תִֽהְיֶ֥ה לָהֶ֖ם לְאִ֣ישׁ מוֹכִ֑יחַ כִּ֛י בֵּ֥ית מְרִ֖י הֵֽמָּה׃
내가 네 혀로 네 입천장에 붙게 하여 너로 벙어리 되어 그들의 책망자가 되지 못하게 하리니 그들은 패역한 족속임이니라
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.
