They conceive mischief, and bring forth vanity, and their belly prepareth deceit. They conceive mischief - The figure here is both elegant and impressive. The wicked conceive mischief, from the seed which Satan sows in their hearts; in producing which they travail with many pangs, (for sin is a sore labor), and at last their womb produces fraud or deception. This is an accursed birth, from an iniquitous conception. St. James gives the figure at full length, most beautifully touched in all its parts: When lust hath conceived it bringeth forth sin; and sin, when it is finished, bringeth forth death; James 1:15 (note), where see the note. Poor Job! what a fight of affliction had he to contend with! His body wasted and tortured with sore disease; his mind harassed by Satan; and his heart wrung with the unkindness, and false accusations of his friends. No wonder he was greatly agitated, often distracted, and sometimes even thrown off his guard. However, all his enemies were chained; and beyond that chain they could not go. God was his unseen Protector, and did not suffer his faithful servant to be greatly moved.
