This verse closes the mother's counsel, Proverbs 31:1–9.
Quick answer
The counsel's last words: open your mouth, judge righteously, plead for the poor and needy. A mother's whole brief for a king lands in three verbs of advocacy.
Read the whole unit
The book's last chapter opens with a unique voice: the words of King Lemuel, "the utterance which his mother taught him." Lemuel appears nowhere else in Scripture, and the counsel he carries is the only teaching in Proverbs explicitly credited to a woman. Its structure is a queen mother's brief: the triple address of maternal urgency (v. 2), then three dangers ranked by what they cost a king: women who consume royal strength (v. 3), wine that clouds royal judgment (vv. 4–5, with a sharp aside on where strong drink might mercifully go instead, vv. 6–7), and finally the positive charge that everything was protecting: open your mouth for the speechless, judge righteously, plead the cause of the poor and needy (vv. 8–9). The logic runs on vocation. A king's strength, clarity, and voice are not his own; they are held in trust for people who have none of the three. The unit ends, and the acrostic begins, and the book closes with the counsel of a mother followed by the praise of a woman, wisdom's last two teachers both unexpected and both unforgettable.
What this verse contributes
This verse contributes the summation, and it repeats "open your mouth" so the command cannot be filed as suggestion. Judging righteously and pleading for the poor are placed in apposition, one job described twice, because in this counsel just judgment and advocacy for the needy are not two duties in tension but one duty seen whole. It is the Old Testament's compact theology of power: measured not by what it accumulates but by whom it defends (Jeremiah 22:16 says of a good king, "he judged the cause of the poor and needy... was not this knowing Me?"). The mother finishes, and the book immediately turns to its final poem, praise of a woman of valor, as though to show the son one more time what strength spent rightly looks like.
