33 The use of the demonstrative pronoun is enclitic, serving as an undeclined particle for emphasis. It gives the sense of “What in the world have you done?” (see R. J. Williams, Hebrew Syntax, 24, §118).
34 The Hebrew word order puts the subject (“the serpent”) before the verb here, giving prominence to it.
35 This verb (the Hiphil of נָשָׁא, nasha) 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).
