Geneva Bible Notes Reformed @genevanotes

The mouth of strange women [is] a deep pit: he that is abhorred by the LORD shall fall in it. (k) So God punishes one sin by another, when he suffers the wicked to fall into the acquaintance of a harlot.

Jamieson-Fausset-Brown Reformed @jfbcommentary

The mouth--or flattering speeches (Pro 5:3; Pro 7:5) ensnare man, as pits, beasts. God makes their own sin their punishment.

Matthew Henry Presbyterian @wholebiblehenry

This is designed to warn all young men against the lusts of uncleanness. As they regard the welfare of their souls, let them take heed of strange women, lewd women, whom they ought to be strange to, of the mouth of strange women, of the kisses of their lips (Pro 7:13), of the words of their lips, their charms and enticements.
