פֶּ֭תִי יַאֲמִ֣ין לְכָל־דָּבָ֑ר וְ֝עָר֗וּם יָבִ֥ין לַאֲשֻׁרֽוֹ׃
愚蒙人凡話都信；精明人卻謹慎察看自己的腳步。
Rashi
A fool believes their words and is enticed after them. Another explanation: with laughter the heart aches It is sport for a fool to carry out a sinful plot (above 10:23), and ultimately, his heart will ache. The one with an impure heart is a wicked man, as in (below 26:23) “Impure (סיגים) silver.” סיג is the name of the dross. סוג is the silver mixed with the dross.
Rashi
and above him is a good man And above the wicked man will be the righteous man.
Rashi
but a cunning man understands his steps Heb. לאשרו, his steps. He waits to quarrel until he knows the matter correctly.
