³ tn The word means “deception,” but some suggest “self-deception” here (W. McKane, Proverbs [OTL], 466; and D. W. Thomas, “Textual and Philological Notes on Some Passages in the Book of Proverbs,” VTSup 3 [1955]: 286); cf. NLT “fools deceive themselves.” The parallelism would favor this, but there is little support for it. The word usually means “craft practiced on others.” If the line is saying the fool is deceitful, there is only a loose antithesis between the cola.

³ tn This verb (the Hiphil of נָשָׁא, nashaʾ) is used elsewhere of a king or god misleading his people into false confidence (2 Kgs 18:29 = 2 Chr 32:15 = Isa 36:14; 2 Kgs 19:10 = Isa 37:10), of an ally deceiving a partner (Obad 7), of God deceiving his sinful people as a form of judgment (Jer 4:10), of false prophets instilling their audience with false hope (Jer 29:8), and of pride and false confidence producing self-deception (Jer 37:9; 49:16; Obad 3).
