Let not him that is deceived trust in vanity: for vanity shall be his recompence.
Ver. 31. Let not him that is deceived trust in vanity] Let it suffice him that he hath been once already deceived by the uncertainty of riches, which were never true to those which trusted them, nor ever will be, 1 Timothy 6:17. As Charondas was wont to say of going to sea, and another of going to law, That he wondered not at those that go once, but at those who go a second time. So may we at those that having found the deceitfulness of sin, and the instability of creature comforts, that they should again be drawn in and deceived. This folly Eliphaz here forewarneth Job of, and would not have him twice stumble at the same stone, but deliver his soul, if ever God should restore him again, and say, "Is there not a lie in my right hand?" Why feed I upon ashes? &c., Isaiah 44:20 .
For vanity shall be his recompense] i.e. Poverty and misery shall be his portion, as shame shall be the portion of fools, Proverbs 3:35. As he hath sowed the wind, so he shall reap the whirlwind, whereof he is likely to have a great catch, Hosea 8:7; See Trapp on " Hos 8:7 "
