Bridges on Proverbs 31:1-2
Charles Bridges on Proverbs 31:1-2

1.  The words of king Lemuel, the prophecy that his mother taught him. 2.  What, my son? and what, the son of my womb? and what, the son of my vows?
OF King Lemuel we know no more than of the prophet Agur in the last Chapter.† All that we know is, that he was endowed, like many of God’s people (Psalm 116:16. 2 Timothy 1:5; 3:15), with the invaluable blessing of a godly mother; who, like Deborah of old (Judges 5:1), was honored of God to be the author of a chapter of the sacred volume.
What an animating burst from the yearning of a mother’s heart! What! my son — the son of my womb — of my vows? Happy mother — when the son of her womb is the son of her vows! like Samuel, a dedicated child, a child of many prayers; “asked of the LORD, lent unto his service.” (1 Samuel 1:11.) If there were more Hannahs, would there not be more Samuels? If thou wouldst have, Christian mother, thy child a Samuel or an Augustine, be thyself a Hannah or a Monica. The child of thy prayers, of thy vows, and of thy tears, will be in the Lord’s best time the child of thy praises, thy rejoicings, thy richest consolation. Yet thy faith will not end with the dedication of thy child. Lemuel — the son of her vows — his mother taught him. And such is the practical habit of godliness, that faith in vowing quickens diligence in teaching. The child, truly consecrated, will be “brought up in the nurture and admonition of the Lord.” (Ephesians 6:4.)
