Benson Commentary

"Proverbs 31:3. Give not thy strength unto women — The vigour of thy mind and body, which is greatly impaired by inordinate lusts, as all physicians agree, and frequent experience shows; nor thy ways — Thy conversation or course of life; to that which destroyeth kings — "

Gill's Exposition of the Entire Bible

"Give not thy strength unto women,.... Strength of body, which is weakened by an excessive use of venery (b) with a multiplicity of women; see, Proverbs 5:9; and strength of mind, reason, and wisdom, which is impaired by conversation with such persons; whereby time is consumed and lost, which should be spent in the improvement of knowledge: or "thy riches", as the Septuagint and Arabic versions, thy substance, which harlots devour, and who bring a man to a piece of bread, as the prodigal was, Proverbs 6:26; and even drain the coffers of kings and princes;"
