Hearken unto thy father that begat thee, and despise not thy mother when she is old.

Hearken to thy father, that beget thee: and despise not thy mother when she is old.

Hearken to thy father, who begat thee, And despise not thy mother when she hath become old.

Give ear to your father whose child you are, and do not keep honour from your mother when she is old.

Hearken unto thy father that begot thee, And despise not thy mother when she is old.

Listen to your father, who conceived you. And do not despise your mother, when she is old.

Despise not thy mother when she is old - A very necessary caution, as very old women are generally helpless, useless, and burdensome: yet these circumstances do not at all lessen the child's duty. And this duty is strengthened by the Divine command here given.

Hearken unto thy father that begat thee,.... And who has a true and hearty affection for thee, and whatever he says is for thy good and welfare, which he studies and has at heart; and who therefore also has an authority over thee, and what he enjoins ought to be strictly regarded; and, having lived longer in the world, must be thought to have a larger experience and knowledge of things, and therefore should be hearkened unto;
and despise not thy mother when she is old; despise not her counsels, instructions, and advice, though she is old; and because she is so, do not reject them as old wives' fables, or as the silly talk of an old woman, as young men are too apt to do.

Hearken--that is, obey (Proverbs 1:8; Ephesians 6:1).
despise . . . old--Adults revere the parents whom, as children, they once obeyed.

The parainesis begins anew, and the division is open to question. Proverbs 23:22-24 can of themselves be independent distichs; but this is not the case with Proverbs 23:25, which, in the resumption of the address and in expression, leans back on Proverbs 23:22. The author of this appendix may have met with Proverbs 23:23 and Proverbs 23:24 (although here also his style, as conformed to that of Proverbs 1:9, is noticeable, cf. 23b with Proverbs 1:2), but Proverbs 23:22 and Proverbs 23:25 are the form which he has given to them.
Thus Proverbs 23:22-25 are a whole: -
22 Hearken to thy father, to him who hath begotten thee,
And despise not thy mother when she has grown old.
23 Buy the truth, and sell it not,
Wisdom and discipline and understanding.
24 The father of a righteous man rejoiceth greatly;
(And) he that is the father of a wise man - he will rejoice.
25 Let thy father and thy mother be glad;
And her that bare thee exult.
The octastich begins with a call to childlike obedience, for שׁמע ל, to listen to any one, is equivalent to, to obey him, e.g., Psalm 81:9, Psalm 81:14 (cf. "hearken to his voice," Psalm 95:7). זה ילדך is a relative clause (cf. Deuteronomy 32:18, without זה or אשׁר), according to which it is rightly accentuated (cf. on the contrary, Psalm 78:54). 22b, strictly taken, is not to be translated neve contemne cum senuerit matrem tuam (Fleischer), but cum senuerit mater tua, for the logical object to אל־תּבוּז is attracted as subj. of זקנה (Hitzig). There now follows the exhortation comprehending all, and formed after Proverbs 4:7, to buy wisdom, i.e., to shun no expense, no effort, no privation, in order to attain to the possession of wisdom; and not to sell it, i.e., not to place it over against any earthly possession, worldly gain, sensual enjoyment; not to let it be taken away by any intimidation, argued away by false reasoning, or prevailed against by enticements into the way of vice, and not to become unfaithful to it by swimming with the great stream (Exodus 23:2); for truth, אמת, is that which endures and proves itself in all spheres, the moral as well as the intellectual. In 23b, in like manner as Proverbs 1:3; Proverbs 22:4, a threefold object is given to קנה instead of אמת: there are three properties which are peculiar to truth, the three powers which handle it: חכמה is knowledge solid, pressing into the essence of things; מוּסר is moral culture; and בּינה the central faculty of proving and distinguishing (vid., Proverbs 1:3-5). Now Proverbs 23:24 says what consequences are for the parents when the son, according to the exhortation of Proverbs 23:23, makes truth his aim, to which all is subordinated. Because in אמת the ideas of practical and theoretical truth are inter-connected. צדּיק and חכם are also here parallel to one another. The Chethı̂b of 24a is גּול יגוּל, which Schultens finds tenable in view of (Arab.) jal, fut jajûlu (to turn round; Hebrews. to turn oneself for joy) but the Hebrews. usus loq. knows elsewhere only גּיל יגיל, as the Kerı̂ corrects. The lxx, misled by the Chethı̂b, translates καλῶς ἐκτρέφει (incorrect ἐκτρυφήσει), i.e., גּדּל יגדּל. In 24b, וישׂמח is of the nature of a pred. of the conclusion (cf. Genesis 22:24; Psalm 115:7), as if the sentence were: has one begotten a wise man, then (cf. Proverbs 17:21) he has joy of him; but the Kerı̂ effaces this Vav apodosis, and assigns it to יולד as Vav copul. - an unnecessary mingling of the syntactically possible, more emphatic expression. This proverbial whole now rounds itself off in Proverbs 23:25 by a reference to Proverbs 23:22 - the Optative here corresponding to the Impr. and Prohib. there: let thy father and thy mother rejoice (lxx εὐφρανέσθω), and let her that bare thee exult (here where it is possible the Optat. form ותגל).
