For the director of music. A maski] of David. When Doeg the Edomite had gone to Saul and told him: “David has gone to the house of Ahimelek.”

1 Why do you boast of evil, you mighty hero?
    Why do you boast all day long,
    you who are a disgrace in the eyes of God?
2 You who practice deceit,
    your tongue plots destruction;
    it is like a sharpened razor.
3 You love evil rather than good,
    falsehood rather than speaking the truth.
4 You love every harmful word,
    you deceitful tongue!

5 Surely God will bring you down to everlasting ruin:
    He will snatch you up and pluck you from your tent;
    he will uproot you from the land of the living.
6 The righteous will see and fear;
    they will laugh at you, saying,
7 “Here now is the man
    who did not make God his stronghold
but trusted in his great wealth
    and grew strong by destroying others!”

8 But I am like an olive tree
    flourishing in the house of God;
I trust in God’s unfailing love
    for ever and ever.
9 For what you have done I will always praise you
    in the presence of your faithful people.
And I will hope in your name,
    for your name is good. (NIV)

I wonder, how many Doeg’s have there been in human history, and how many there are still, who grow ”strong by destroying others”? But at the end of the day, the ”righteous” have the last laugh. The Doeg’s will have their catastrophic downfalls. Let’s keep this in mind as we are troubled by the news, and maybe, more particularly, suffer at their hands personally. There is a ”Surely” about their ruin. God’s justice will prevail

There is such a contrast in verses 8,9. David can know what Doeg is up to, but just be full of confidence in God. We too can live in this wicked world with a relaxed, and happy confidence in God.

‘For his part, David expects to be blessed by God. While Doeg will be “uprooted” (Psalm 52:5), David is firmly planted in God’s will. He compares this to an olive tree, which can live a long, productive life (Psalm 1:3). Scripture does not include any resolution to Doeg’s story; we are not told if or when he suffered retribution for his crimes. Yet such judgment is inevitable—either in earthly life or in eternity (Proverbs 11:4; 2 Thessalonians 1:7–10; Hebrews 4:13; Revelation 20:11–15). Anticipating this, though it had not yet happened, David resolves to join other believers in praise and worship (Psalm 52:8–9).’ Bible Ref

‘The inscription of this psalm describes its origin. The contrast which it presents is full of instruction. The ungodly is often a mighty man in the estimation of the world. He boasts mischief; his tongue resembles the razor, which inflicts sharp and deep wounds; his words devour reputations, family-peace, and souls.

What a contrast is presented by the humble believer who trusts, not in wealth which vanishes, but in God’s mercy which abides forever! Psalms 52:1-8 . As the olives grew around the humble forest sanctuary at Nob, where the tragedy which called forth this psalm took place, and were hallowed by the shrine they encompassed, so the believer grows and is safe in loving fellowship with his Almighty Friend. Let us be among God’s evergreens, drawing our nutriment from Him, as the roots struck into the rich mold. The psalmist is so certain of vindication and so assured of the overthrow of wickedness that he celebrates God’s interposition before it takes place, and accounts it as being already accomplished.’ F.B.Meyer
