Job 15:31

The verse reads,

Let him not trust in vanity: he is deceived:

For vanity shall be his recompence.

Similarly, "they that plow iniquity reap the same," ch. Job 4:8; Job 5:13. Eliphaz returns as in other passages to his former speech. "Vanity" or evil means both wickedness (first clause) and calamity or trouble (second clause). The word "recompence" means exchange, that received in barter or return.
