כִּ֣י יָגֹ֗רְתִּי מִפְּנֵ֤י הָאַף֙ וְהַ֣חֵמָ֔ה אֲשֶׁ֨ר קָצַ֧ף יְהוָ֛ה עֲלֵיכֶ֖ם לְהַשְׁמִ֣יד אֶתְכֶ֑ם וַיִּשְׁמַ֤ע יְהוָה֙ אֵלַ֔י גַּ֖ם בַּפַּ֥עַם הַהִֽוא׃
For I was in dread of the anger and hot displeasure, wherewith the LORD was wroth against you to destroy you. But the LORD hearkened unto me that time also.
