Adam Clarke's Bible Commentary Verse 9. No faithfulness in their mouth ] They make professions of friendship; but all is hollow and deceitful: "They flatter with their tongue." Very wickedness - Their heart is full of all kinds of depravity.
Their throat is an open sepulcher ] It is continually gaping for the dead; and sends forth effluvia destructive to the living. I fear that this is too true a picture of the whole human race, totally corrupt within, and abominable without. The heart is the center and spring of this corruption; and the words and actions of men, which proceed from this source, will send out incessant streams of various impurity; and thus they continue till the grace of God changes and purifies the heart.
Matthew Henry Commentary
Verses 7-12 - David prayed often alone, yet was very constant in attendance on publi worship. The mercy of God should ever be the foundation both of ou hope and of our joy, in every thing wherein we have to do with him. Le us learn to pray, not for ourselves only, but for others; grace be with all that love Christ in sincerity. The Divine blessing comes down upo us through Jesus Christ, the righteous or just One, as of old it di upon Israel through David, whom God protected, and placed upon the throne. Thou, O Christ, art the righteous Saviour, thou art the King of Israel, thou art the Fountain of blessing to all believers; thy favou is the defence and protection of thy church _________________________________________________
