יִֽשְׂמְח֥וּ וִֽירַנְּנ֗וּ לְאֻ֫מִּ֥ים כִּֽי־תִשְׁפֹּ֣ט עַמִּ֣ים מִישׁ֑וֹר וּלְאֻמִּ֓ים ׀ בָּאָ֖רֶץ תַּנְחֵ֣ם סֶֽלָה׃
O let the nations be glad and sing for joy; For Thou wilt judge the peoples with equity, And lead the nations upon earth. Selah
Rashi on Psalms
You will lead them You will lead them in a fair way; therefore, all peoples will thank You.
