Sprüche 27:11

This proverb has, in common with the preceding tristich, the form of an address: Become wise, my son, and make my heart rejoice, That I may give an answer to my accusers. Better than "be wise" (Luther), we translate "become wise" (lxx σοφὸς γίνου); for he who is addressed might indeed be wise, though not at present so, so that his father is made to listen to such deeply wounding words as these, "Cursed be he who begat, and who educated this man" (Malbim). The cohortative clause 11b (cf. Psa 119:42) has the force of a clause with a purpose (Gesen. 128:1): ut habeam quod iis qui me convicientur regerere possim; it does not occur anywhere in the Hezekiah collection except here.

Children are here exhorted to be wise and good, 1. That they may be a comfort to their parents and may make their hearts glad, even when the evil days come, and so recompense them for their care, Pro 23:15. 2. That they may be a credit to them: "That I may answer him that reproaches me with having been over-strict and severe in bringing up my children, and having taken a wrong method with them in restraining them from the liberties which other young people take. My son, be wise, and then it will appear, in the effect, that I went the wisest way to work with my children." Those that have been blessed with a religious education should in every thing conduct themselves so as to be a credit to their education and to silence those who say, A young saint, an old devil; and to prove the contrary, A young saint, an old angel.

27:11 Fairly or not, parents are evaluated by their children’s public behavior.
