Job 20:1-3

Zophar’s anger 20:1-3

"Therefore" (Job 20:2) must refer to what Job had said. Job had previously asked why his friends answered him (Job 16:3). Zophar replied that the spirit of his understanding made him answer (Job 20:3 b).

"This phrase means both that Zophar’s spirit is compelling him to respond to Job (c. Job 32:18) and that his words come from reasoned insight (cf. Fohrer)." [Note: Ibid., p. 300.]

Again he seems to be claiming innate, instinctive knowledge (cf. ch. 11).
