John Gill Commentary Proverbs 31:2

"What, my son? and what, O son of my womb? And what, O son of my vows?" — Proverbs 31:2 (ASV)

What, my son ?
&c.] What shall I call you? though you are a king, can I address you in more suitable language, or use a more endearing appellative than this, and what follows? permit me, your mother, to speak to you as my son: and what shall I say to you? I want words, I want wisdom; O that I knew what to say to you, that would be proper and profitable; or what is it I am about to say to you? things of the greatest moment and importance, and therefore listen to me; and so the manner of speaking is designed to excite attention: or what shall I ask of you? no part of your kingdom, or any share in the government of it; only this favour, to avoid the sins unbecoming a prince, and to do the duty of a king, later mentioned. The Targum and Syriac version represent her as exclaiming, reproving, and threatening; as, Alas my son! is this the life you design to live, to give up yourself to wine and women? fie upon it, my son, is this becoming your birth, education, and dignity? is this the fruit of all the pains I have taken in bringing you up? consider the unbecoming part you are acting;

and what, the son of my womb ?
whom I bore in sorrow, brought forth in pain, and took so much care and trouble to bring up in a religious way, and form for usefulness in church and state? not an adopted son, but my own flesh and blood; and therefore what I say must be thought to proceed from pure affection to you, and solely for your good; see (Isaiah 49:15) ;

and what, the son of my vows ?
whom I asked of God, and promised to give up to him again, and did; for which reason she might call him Lemuel, as Hannah called her son Samuel, for a like reason, (1 Samuel 1:28) ; a son for whom she had put up many prayers, for his temporal and spiritual good; and on whose account she had made many vows, promises, and resolutions, that she would do so and so, should she be so happy as to bring him into the world, and bring him up to man's estate, and see him settled on the throne of Israel.
