Rashi on Proverbs
My son, cease to stray, etc. This is an elliptical verse, and this is its explanation: My son, cease to stray from words of knowledge in order to hear discipline.
Rashi on Proverbs
cease to stray Heb. לשגות, like מלשגות, from straying. Likewise, (Num. 9:13): “and refrains (וחדל) from performing (לעשות) the Passover service.” Also, (Gen. 41:49): “they stopped counting (לספר).”
