Job 42:2 - Wesley's Explanatory Notes

Thou canst, &c. — Job here subscribes to God's unlimited power, knowledge and dominion, to prove which was the scope of God's discourse out of the whirlwind. And his judgment being convinced of these, his conscience also was convinced, of his own folly in speaking so irreverently concerning him. No thought can be withholden from thee — No thought of ours can be withholden from thy knowledge. And there is no thought of thine, which thou canst be hindered from bringing into execution.
