Job 20:20 tn Heb “belly,” which represents his cravings, his desires and appetites. The “satisfaction” is actually the word for “quiet; peace; calmness; ease.” He was driven by greedy desires, or he felt and displayed an insatiable greed.

Job 20:20 tn The verb is difficult to translate in this line. It basically means “to cause to escape; to rescue.” Some translate this verb as “it is impossible to escape”; this may work, but is uncertain. Others translate the verb in the sense of saving something else: N. Sarna says, “Of his most cherished possessions he shall save nothing” (“The Interchange of the Preposition bet and min in Biblical Hebrew,” JBL 78 [1959]: 315-16). The RSV has “he will save nothing in which he delights”; NIV has “he cannot save himself by his treasure.”
