¹ sn The word describes a slanderer (NASB), a tale-bearer (KJV, ASV), or an informer. BDB 940 s.v. רָכִיל says the Hebrew expression “goers of slander” means slanderous persons. However, W. McKane observes that these people are not necessarily malicious – they just talk too much (Proverbs [OTL], 537).

² tn The form is the Hitpael imperfect (of prohibition or instruction) from עָרַב (’arav). BDB 786-88 lists six roots with these radicals. The first means “to mix,” but only occurs in derivatives. BDB 786 lists this form under the second root, which means “to take on a pledge; to exchange.” The Hitpael is then defined as “to exchange pledges; to have fellowship with [or, share].” The proverb is warning people to have nothing to do with gossips.

³ tn The verb פֹּתֶה (poteh) is a homonym, related to I פָּתָה (patah, “to be naive; to be foolish”; HALOT 984-85 s.v. I פתה) or II פָּתָה (“to open [the lips]; to chatter”; HALOT 985 s.v. II פתה). So the phrase וּלְפֹתֶה שְׂפָתָיו may be understood either (1) as HALOT 985 s.v. II פתה suggests, “one opens his lips” = he is always talking/gossiping, or (2) as BDB suggests, “one who is foolish as to his lips” (he lacks wisdom in what he says; see BDB 834 s.v. פָּתָה 1, noted in HALOT 984 s.v. I פתה 1). The term “lips” is a metonymy of cause for what is said: gossip. If such a person is willing to talk about others, he will be willing to talk about you, so it is best to avoid him altogether.

⁴ tn Most commentators (and some English versions, e.g., NIV) assume that the participle מְפַחֵד (mÿfakhed, “fears”) means “fears the Lord,” even though “the Lord” is not present in the text. Such an assumption would be more convincing if the word יִרְאַת (yir’at) had been used. It is possible that the verse refers to fearing sin or its consequences. In other words, the one who is always apprehensive about the nature and consequences of sin will avoid sin and find God’s blessing. Of course the assumption that the phrase means “fear the Lord” could be correct as well. There would be little difference in the outcome; in either case sin would be avoided.

⁵ sn The one who “hardens his heart” in this context is the person who refuses to fear sin and its consequences. The image of the “hard heart” is one of a stubborn will, unyielding and unbending (cf. NCV, TEV, NLT). This individual will fall into sin.
