וְה֗וּא יִשְׁפֹּֽט־תֵּבֵ֥ל בְּצֶ֑דֶק יָדִ֥ין לְ֝אֻמִּ֗ים בְּמֵישָׁרִֽים׃
他必按公義審判世界，以正直為萬民施行審判。
Rashi
But He judges the world with righteousness, kingdoms with equity Until the coming of the end, He was wont to judge them with clemency according to the equity found in them. He would judge them at night, when they would sleep and commit no sins.
Radak
And He shall judge the world in righteousness, He shall minister judgment to the people in equity. – תבל (world) is the inhabited part. He says: As He will judge my cause in righteousness, so He judges the peoples in righteousness and in equity always and at all times; and when one people prevails over another it is (equally) a judgment from Him.
