Proverbs 23:27 tn Heb “foreign woman” (so ASV). The term נָכְרִיָּה (nokhriyyah, “foreign woman”) often refers to a prostitute (e.g., Prov 2:6; 5:20; 6:24; 7:5). While not all foreign women in Israel were prostitutes, their prospects for economic survival were meager and many turned to prostitution to earn a living. Some English versions see this term referring to an adulteress as opposed to a prostitute (cf. NAB, NASB, NIV, NRSV, NLT).

Proverbs 23:27 sn In either case, whether a prostitute or an adulteress wife is involved, the danger is the same. The metaphors of a “deep pit” and a “narrow well” describe this sin as one that is a trap from which there is no escape. The “pit” is a gateway to Sheol, and those who enter are as good as dead, whether socially or through punishment physically.
