וַיְהִי֙ ק֣וֹל הַשּׁוֹפָ֔ר הוֹלֵ֖ךְ וְחָזֵ֣ק מְאֹ֑ד מֹשֶׁ֣ה יְדַבֵּ֔ר וְהָאֱלֹהִ֖ים יַעֲנֶ֥נּוּ בְקֽוֹל׃
And when the voice of the horn waxed louder and louder, Moses spoke, and God answered him by a voice.
Targum Jonathan on Exodus
And the voice of the trumpet went forth, and grew stronger: (then) Mosheh spake, and was answered from before the Lord with a gracious and majestic voice, and with pleasant and gracious words.
