Be wise, my child, and bring joy to my heart; then I can answer anyone who treats me with contempt. (NIV)
My son, be wise, and make my heart glad, that I may answer him who reproaches me [as having failed in my parental duty]. [Prov. 10:1; 23:15, 24.] (AMP)
My son, be wise, and make my heart glad, that I may answer him that reproacheth me. (KJV)
