Job 5:2

“For wrath killeth the foolish man, etc.] Not one that is an idiot, and destitute of common sense, and has no understanding in things natural and civil; but a wicked man, who has no knowledge of things divine and spiritual, and so foolish; which is the character of every natural man, and of God’s people before conversion; and even of some professors, who are foolish virgins, and carry the lamp of a religious profession without the oil of grace; and such an one Eliphaz took Job to be, whom sooner or later the wrath of the Lord, as the Targum interprets it, which is revealed from heaven, and comes down upon the children of disobedience, would consume like devouring fire: or this may be…”

The foolish - The rash and inconsiderate man, who does not weigh things impartially. Envy, &c. - I perceive thou art full of envy at wicked men, who seem to be in a happier condition than thou, and of wrath against God; and this shews thee to be a foolish and weak man. For those men, notwithstanding their present prosperity, are doomed to great and certain misery. I have myself seen the proof of this. Job 5:3”

“wrath: Job 18:4; Jon 4:9 the foolish: Psa 14:1, Psa 75:4, Psa 92:6, Psa 107:17; Pro 1:22, Pro 1:23, Pro 8:5; Ecc 7:9 envy: or, indignation, Gen 30:1; Sa1 18:8, Sa1 18:9; Rom 2:8 one: Hos 7:11; Ti2 3:6 Job 5:3”
