2. The ground of their security. They trusted in their wickedness and in their wisdom, v. 10. (1.) Their power and wealth, which they had gotten by fraud and oppression, were their confidence: Thou hast trusted in thy wickedness, As Doeg. Ps. lii. 7. Many have so debauched their own consciences, and have got to such a pitch of daring wickedness, that they stick at nothing; and this they trust to carry them through those difficulties which embarrass men who make conscience of what they say and do. They doubt not but they shall be too hard for all their enemies, because they dare lie, and kill, and forswear themselves, and do any thing for their interest. Thus they trust in their wickedness to secure them, which is the only thing that will ruin them. (2.) Their policy and craft, which they called their wisdom, were their confidence. They thought they could outwit all mankind, and therefore might set all their enemies at defiance. But their wisdom and knowledge perverted them, and turned them out of the way, made them forget themselves, and the preparation necessary to be made for hereafter.
