קְרָ֤א בְגָרוֹן֙ אַל־תַּחְשֹׂ֔ךְ כַּשּׁוֹפָ֖ר הָרֵ֣ם קוֹלֶ֑ךָ וְהַגֵּ֤ד לְעַמִּי֙ פִּשְׁעָ֔ם וּלְבֵ֥ית יַעֲקֹ֖ב חַטֹּאתָֽם׃
你要放聲呼喊，不要停止；要高聲如吹角，向我的百姓宣告他們的過犯，向雅各家宣告他們的罪惡。
Rashi
and relate to My people their transgression These are the Torah scholars, whose every inadvertent sin is counted as a transgression, for an error in study is accounted as an intentional sin.
Ibn Ezra
Cry aloud. The prophet is addressed by God. אל תחשך Spare not the crying; the objective case must be supplied, because חשך is a transitive verb.
Rashi
and to the house of Jacob their sins These are the ignorant people, whose willful sins, are accounted inadvertent.
