כִּ֣י אִם־בְּזֹ֞את יִתְהַלֵּ֣ל הַמִּתְהַלֵּ֗ל הַשְׂכֵּל֮ וְיָדֹ֣עַ אוֹתִי֒ כִּ֚י אֲנִ֣י יְהוָ֔ה עֹ֥שֶׂה חֶ֛סֶד מִשְׁפָּ֥ט וּצְדָקָ֖ה בָּאָ֑רֶץ כִּֽי־בְאֵ֥לֶּה חָפַ֖צְתִּי נְאֻם־יְהוָֽה׃ (ס)
But let him that glorieth glory in this, that he understandeth, and knoweth Me, That I am the LORD who exercise mercy, justice, and righteousness, in the earth; for in these things I delight, Saith the LORD.
