Charles Ellicott Commentary Job 20:18

"That which he labored for shall he restore, and shall not swallow it down; According to the substance that he hath gotten, he shall not rejoice." — Job 20:18 (ASV)

That which he laboured for shall he restore ... (Job 20:18)—The latter part of this verse is probably right; but it may be, According to the substance that he has gotten he shall not rejoice.
