The wise [men] are ashamed, they are dismayed and taken: lo, they have rejected the word of the LORD; and what wisdom [is] in them?
Ver. 9. The wise men are ashamed.] They have cause to be ashamed of their gross ignorance and folly, Jer 8:7-8 and greater cause than ever humble Augustine had to say, Scientia mea me damnat, My knowledge undoeth me.
Lo, they have rejected the word of the Lord.] As to any holy practice, their knowledge is only apprehensive and notional, not affective and practical.
And what wisdom is in them?] q.d., None worth speaking of; they lose their civil praises, because not wise to salvation.
