This is designed to engage us to diligence, and quicken us, what our hand finds to do, to do it with all our might, both in our worldly business and in the work of religion; for in the original it is, The soul that labours labours for itself. It is heart-work which is here intended, the labour of the soul, which is here recommended to us, 1. As that which will be absolutely needful. Our mouth is continually craving it of us; the necessities both of soul and body are pressing, and require constant relief, so that we must either work or starve. Both call for daily bread, and therefore there must be daily labour; for in the sweat of our face we must eat, Th2 3:10. 2. As that which will be unspeakably gainful. We know on whose errand we go: He that labours shall reap the fruit of his labour; it shall be for himself; he shall rejoice in his own work and eat the labour of his hands. If we make religion our business, God will make it our blessedness.

An ungodly man diggeth up evil,.... Or "a man of Belial" (p), a worthless unprofitable man; a man without a yoke, not obedient to the law of God; such a man digs for sin as for a treasure; nor need he go far for it, he has enough in his own heart, out of the evil treasure of which he brings forth evil things; though he is more solicitious and diligent to search into the sins of others, and dig up them, which have long lain buried; as the Manichees raked up the sins of Austin in his youth; and as the Papists served Beza: but perhaps the evil of mischief is here rather intended, which a wicked man contrives and devises; a ditch he digs for others, though oftentimes he falls into it himself; and so the Septuagint and Arabic versions render it, "digs evils for himself"; not intentionally but eventually; see Psa 7:15;

and in his lips there is as a burning fire; his tongue is a fire, it is set on fire of hell, and it sets on fire the course of nature; and with its lies, calumnies, and detractions, devours and consumer the good names, characters, and credit of men; and deserves no other than sharp arrows of the Almighty, and coals of juniper; even the everlasting fire and flames of hell, Jam 3:6.

Diligence is a duty due to one's self, for his wants require labor.
