וְ֭עַתָּה מְלָכִ֣ים הַשְׂכִּ֑ילוּ הִ֝וָּסְר֗וּ שֹׁ֣פְטֵי אָֽרֶץ׃
그런즉 군왕들아 너희는 지혜를 얻으며 세상의 관원들아 교훈을 받을지어다
Rashi
And now, [you] kings, be wise The Jewish prophets are merciful people. They reprove the heathens to turn away from their evil, for the Holy One, blessed be He, extends His hand to the wicked and to the righteous.
Radak
Now therefore, O ye kings: – David said to them, to the kings who came to fight him, “O kings!”
Ibn Ezra
And now, O kings (וְ֭עַתָּה מְלָכִ֣ים - ve-attah melakhim): These are the "kings of the earth" [mentioned in verse 2].
