Proverbs 29:15

"The rod and reproof give wisdom; But a child left to himself causeth shame to his mother."

Proverbs 13:24 and Proverbs 23:13 also deal with discipline for children. See comments under similar proverbs. In several other disciplinary instructions, the undisciplined son is said to cause shame, grief, etc. to his father; and the wise or well-disciplined son is said to bring joy to his father. See Proverbs 17:21 and Proverbs 23:24-25. Toy noted that, "The mother might have been mentioned here (1) because she is charged with the principal duty of rearing the child, or (2) merely for rhetorical purposes."[21] Really, what is said of either parent, in this connection, is certainly true of both.
