פּ֣וֹטֵֽר מַ֭יִם רֵאשִׁ֣ית מָד֑וֹן וְלִפְנֵ֥י הִ֝תְגַּלַּ֗ע הָרִ֥יב נְטֽוֹשׁ׃
爭端的開始，好像開了水閘的缺口；所以在爭吵爆發之前，就當罷手。
Rashi
The beginning of strife is like letting out water Whoever commences a quarrel is like one who opens a hole in the stone walls of a water canal, and the water goes out through it, and the hole becomes progressively wider; so does the quarrel constantly escalate.
Rashi
and before you are exposed Before your shame is exposed, abandon the quarrel.
