The indicative mood unites a declaration with the question: “Do you despise? Aye, you do.”
Riches (πλούτου)
A favorite word with Paul to describe the quality of the divine attributes and gifts. See 2Co 8:9; Eph 1:7, Eph 1:18; Eph 2:4, Eph 2:7; Eph 3:8, Eph 3:16; Phi 4:19; Col 1:27.
Goodness (χρηστότητος)
See on easy, Mat 11:30.
Forbearance and long-suffering (ἀνοχῆς καὶ μακροθυμίας)
Ἁνοχή forbearance, strictly a holding back. In classical Greek mostly of a truce of arms. It implies something temporary which may pass away under new conditions. Hence used in connection with the passing by of sins before Christ (Rom 3:25). “It is that forbearance or suspense of wrath, that truce with the sinner, which by no means implies that the wrath will not be executed at the last; nay, involves that it certainly will, unless he be found under new conditions of repentance and obedience” (Trench). For μακροθυμία long-suffering, see on Jam 5:7. This reliance on God's tolerance to suspend the rule of His administration in your case is contempt (despisest). Compare Gal 6:7.
Not knowing (ἀγνοῶν)
In that thou dost not know. This very ignorance is contempt.
Leadeth (ἄγει)
The continuous present: is leading all the while thou art despising.
