Job 20:13-16 Meaning: The Bitter End of a Sweet Sin
13though he spare it, and will not let it go, but keep it still within his mouth,
14yet his food in his bowels is turned. It is cobra venom within him.
15He has swallowed down riches, and he will vomit them up again. God will cast them out of his belly.
16He will suck cobra venom. The viper’s tongue will kill him.
13Though he spare it, and forsake it not; but keep it still within his mouth:
14Yet his meat in his bowels is turned, it is the gall of asps within him.
15He hath swallowed down riches, and he shall vomit them up again: God shall cast them out of his belly.
16He shall suck the poison of asps: the viper’s tongue shall slay him.
13Though he spare it, and will not let it go, But keep it still within his mouth;
14Yet his food in his bowels is turned, It is the gall of asps within him.
15He hath swallowed down riches, and he shall vomit them up again; God will cast them out of his belly.
16He shall suck the poison of asps: The viper’s tongue shall slay him.
13Hath pity on it, and doth not forsake it, And keep it back in the midst of his palate,
14His food in his bowels is turned, The bitterness of asps is in his heart.
15Wealth he hath swallowed, and doth vomit it. From his belly God driveth it out.
16Gall of asps he sucketh, Slay him doth the tongue of a viper.
13[Though] he spare it, and forsake it not, but keep it within his mouth,
14His food is turned in his bowels; it is the gall of asps within him.
15He hath swallowed down riches, but he shall vomit them up again: God shall cast them out of his belly.
16He shall suck the poison of asps; the viper's tongue shall kill him.
Meaning in one sentence
Job 20:13-16 shows how sin that tastes sweet becomes deadly poison. Zophar's warning: what you cherish can destroy you.
Context
Zophar the Naamathite is the third of Job's friends to speak. In this chapter he insists that the wicked never prosper for long. Their joy is a flash in the pan. The verses before this describe how sin feels good in the mouth, the wicked person keeps it under his tongue, savoring every bit. Then the picture shifts. What went down as food turns into venom inside. Zophar is not just talking about money. He is describing the whole experience of holding on to wrongdoing. The passage uses the body as a map: mouth, throat, stomach, bowels, belly. Everything that seemed pleasant becomes poison. It is a warning written with unforgettable images.
Key Words
Two Hebrew verbs carry the force of this passage. The first is bala, translated "swallowed" in verse 15. It means to gulp down greedily, the way a hungry animal devours prey. The wicked man does not nibble at his sin. He bolts it down. The second verb is qia, "he vomits it up", the body rejecting what it cannot keep. The stomach knows what the mouth refused to admit. One other word matters: merorah, as in the "venom of cobras" in verse 14. The root means bitter. What was sweet going down turns intensely bitter inside. The same word shows up elsewhere in the Old Testament for the bitterness of gall. The point is not a lesson in snake biology. It is a spiritual truth: what looks like a treat on the tongue acts like a toxin once it gets inside you.
How Christians Read This Verse
Christians across traditions have read this passage as a vivid picture of sin's hidden cost. Many Protestant commentators, like Matthew Henry and Albert Barnes, emphasize that sin may give temporary pleasure but will inevitably bring remorse and ruin, a kind of divine poisoning from within. Catholic readers often see the same principle reflected in the Church's teaching on mortal sin: a grievous act chosen with full knowledge destroys grace in the soul, however appealing it seems at the moment. Eastern Orthodox tradition frequently highlights the way sin corrupts the whole person, not just behavior but the inner desires, as the sweetness turns to bitterness. Across these readings, the central point holds: sin deceives us, and its consequences are as real as venom in the bloodstream.
A common misunderstanding
Some readers assume this passage is only about money, that Zophar is describing someone who hoarded wealth and must now repay it. But look at verse 12: it is wickedness itself that is sweet in the mouth. The "riches" in verse 15 are one example, not the whole story. In fact, the passage warns against any cherished sin, a secret grudge, a private habit, an illicit attachment. The poison comes from holding on to what you know is wrong, not just from the size of your bank account.
Living This Out
This week, think about one thing you keep savoring quietly, a resentment you replay, a comparison you feed, a shortcut you tell yourself is harmless. It tastes sweet in the moment. But the passage asks you to trust the nausea before it comes. You do not need to wait until the poison works. You can let go now. That is not weakness. It is wisdom, and it may save your life.
Main takeaway: A sin you hold on to because it feels good will eventually turn into poison that destroys you from the inside.
For Families
For ages 5, 8
Sometimes we want to hold on to something we know is wrong because it feels good. But God says it will make us sick inside. It is better to let go and ask Him to help us choose what is good.
For ages 9, 12
Think of a time you ate too much candy and felt sick afterward. The first bite was great, but your stomach knew the truth. Sin works the same way. The pleasure is real for a moment, but if you keep swallowing it, it turns into poison. God is not trying to take away your fun. He is warning you because He loves you. You can trust Him when He says something will hurt you in the end.
Questions People Ask
Who is speaking in Job 20:13-16?
Zophar the Naamathite, one of Job's three friends. He is arguing that the wicked person's temporary success will be cut short by God's judgment. His speech is part of a larger debate in the book about why the righteous suffer.
What does 'gall of asps' mean in this passage?
It refers to the venom of a poisonous snake, probably a cobra. In ancient thought, the gall (bile) was considered the seat of poison. The image means that something that seemed pleasant to eat becomes deadly inside the body.
Does this passage apply to every sin or only to greed?
The passage begins with 'wickedness' in verse 12, so the context is broader than money. Riches are used as an example in verse 15, but the warning covers any cherished sin, gossip, lust, pride, or dishonesty, that feels sweet but turns harmful.
Is Zophar correct in what he says here, even though Job's friends are often wrong?
The book of Job does not endorse everything the friends say, but this particular warning echoes truths found elsewhere in Scripture: sin deceives and destroys. Many Christians read it as a principle about the nature of sin, even though Zophar misapplies it to Job's situation.
