I. THE ODIOUSNESS OF HIS CHARACTER. It is marked by deceitfulness. Craft and lying are the tools of the betrayer. He cannot get on without them, and he waxes expert in their use. He may pretend friendship, but malice is in his heart. Even if he speaks truth, it is not in love, but in hate. "Whispering tongues can poison truth," Beat on mischief, he does not think of consequences. If he can injure the man he hates, he cares not though the innocent also should suffer. When he comes by a secret, which may be turned to advantage, he is elated. His paltry soul swells within him, he grows big with the idea of his own importance. Life and death are in the power of his tongue. And when his miserable schemes succeed, he boasts as if he had done a brave thing; as if he were the hero of the hour.

II. THE TERRIBLENESS OF HIS DOOM. There was a time when Doeg seemed to succeed. Then he may have blessed his soul, and the men of Saul's court, no doubt, praised him, while he was doing good, as they thought, to himself, and was able to do good to them. But changes came. His real character was unmasked. The fearful results of his treachery were brought to light, and then he must have become the object of detestation to all right-thinking men. It is thus that reputations built on sand fall in the day of trial. The judgment of yesterday may be reversed to-day. The men who stand high to-day may be covered with scorn and infamy to-morrow. God is long-suffering. He even bears long, and strangely, with the wicked. But their day is coming. The judgment described in the psalm is terrible in its completeness. Image is added to image. The metaphors rise in intensity and force. There is not only defeat, as of a house beaten down, but there is expulsion, as from a home made desolate; and more, there is extinction, as of a family rooted out of the land (ver. 5). The overthrow is complete, and all this is by the hand of God, indicating that all deceit and malice and evil-doing are contrary to the Divine order, and doomed in the end to ruin. There is a conscience in society, and, as it is rightly quickened and enlightened, it says "Amen" to God's righteous judgments.

III. THE MORAL LESSONS OF HIS LIFE. There is much here deserving close study. Learn:

1. The justice of God. He is ever on the side of truth. His judgments are all righteous.

2. The folly of sin. (Ver. 7.)

3. The blessedness of the righteous. This lesson is heightened by contrast. How different the tree overthrown, and torn up by the roots, and the "olive tree" standing beautiful and secure in "the house of God" 1 How markedly and utterly separate, the evil-doer judged and put to shame, and the godly man trusting, praising, waiting, rejoicing in the sunshine of God's love, and the hope of his mercy for ever and ever! - W.F

A stern upbraiding addressed to the man who, unscrupulous in the exercise of his power, and proud of his wealth, finds his delight in all the arts of the practised liar.

I. THE ARROGANCE OF A WICKED MAN IN WORLDLY POWER.

1. He boasts of the evil which he does. He is not ashamed of his wickedness.

2. He is bent upon ever new forms of mischief. Works deceitfully, and not openly, and his tongue, as the instrument of his mind, is ever plotting fresh devices of evil.

3. He loves false speaking and false ways more than the true. The wickedness is ingrained, and not merely resorted to for a purpose.

4. He exults in material riches. Thinks they can carry him through, and enable him to brave all consequences.

II. THE CERTAINTY OF HIS OVERTHROW.

1. The goodness of God will ensure it. God loves the good; and his love for them endureth for ever - ensuring the overthrow of the wicked.

2. The sure connection of guilt and punishment. (Ver. 5.) The psalmist had no hesitation in predicting his future fall.

III. THE SYMPATHY WHICH GOOD MEN FEEL WITH GOD'S RIGHTEOUS WORK. (Ver. 6.) They are filled with a holy filial fear; and they rejoice at the triumph of the right and the true over the unjust and the untrue.

IV. GOD'S GOODNESS GIVES CONFIDENCE AND THANKFULNESS TO THE RIGHTEOUS (Vers. 8, 9.) Trust, praise, and patience wait upon thy Name. - S.

The testimony of a saint, confirmed as "good" by all the saints.

I. THE CHARACTER OF THE SAINTS. "I am like a green olive tree." The olive was remarkable for life, beauty, and usefulness. Habakkuk speaks of the "labours of the olive" (Habakkuk 3:17); Jeremiah, of its "goodly fruit" (Jeremiah 11:16); and Hosed, of its "beauty" (Hosea 14:6). It was therefore a fitting symbol of God's people (Romans 11:16), who are adorned with the beauty of holiness, and bear fruit to the praise of God.

II. THE OCCUPATIONS OF THE SAINTS.

1. The first thing named is trusting. "I trust in the mercy of God." The wisdom, the power, the faithfulness, of God all command our trust; but "mercy," what is most needed and always needed, is here singled out. The next thing is:

2. Praising. "I will praise thee for ever." Looking to the past, the present, and the future, countless reasons rise up for praise. What God has done is proof and promise of what he will do.

3. "Waiting is the last thing mentioned. I will wait on thy Name." God's Name is himself, in all that he is and says and does. The more clearly and fully we know God's Name, the more will our hearts go forth to him in love and hope. Waiting upon him ever brings refreshment, and invigorates our souls for new endeavour.

III. THE HOME OF THE SAINTS. "The house of God. So it is here. So it will be hereafter. The saints are happy in their being, secure in their possessions, joyous in their prospects. There are ever light, and sweetness, and holy companionships, and delightful employments, where they dwell. Heaven is their eternal home." - W.F.
