24 The father of the righteous will greatly rejoice;
he who fathers a wise son will be glad in him.
25 Let your father and mother be glad;
let her who bore you rejoice.
From God's Wisdom in Proverbs, 258:
We must not miss that Solomon turns it around and makes this an imperative to the son: you must give joy to your father and mother; you must give your mother reason to rejoice. This is nothing but an application of the imperative in Exodus 20:12, which morally and spiritually obliges children not merely not to dishonor their father and mother, but positively to seek ways to honor them. In that same way, a child is obliged, not only not to bring sorrow and grief to his parents, but positively to seek ways to bring joy and gladness to them.
