כַּ֣עַס לְ֭אָבִיו בֵּ֣ן כְּסִ֑יל וּ֝מֶ֗מֶר לְיוֹלַדְתּֽוֹ׃
A foolish son is vexation to his father, And bitterness to her that bore him.
Rashi on Proverbs
A foolish son causes anger to his father [A foolish son] like Jeroboam causes anger to the Holy One, blessed be He.
Rashi on Proverbs
and bitterness to her who bore him To the people of Israel, whom he caused to sin.
