“To the chief musician upon Mahaleth; a psalm of instruction of David, when Doeg the Edomite went in, and told Saul and said to him, David went to the house of Ahimelech. Why boastest thou thyself in evil, O mighty man? The mercy of God [is] all the day. Thy tongue deviseth mischiefs, as a sharp razor, working deceit. Thou hast loved evil rather than good, falsehood rather than speaking righteousness. Selah. Thou hast loved all words of destruction, O tongue of deceit. God shall also destroy thee forever; he shall take thee away, and pluck thee out of tent, and root thee out of the land of the living. Selah. The righteous also shall see and fear, and laugh at him. Behold the man (strong one) that made not God his strength, but confided in the abundance of his riches; he strengthened himself in his wickedness. But for me, I [am] like a green olive-tree in the house of God; I trust in the mercy of God forever and ever. I will praise thee forever, for thou hast done [it], and I will hope in thy name, for it is good before thy saints (vss. 1-9).
As we had the saints brought to renounce ceremonies as a substitute for righteousness and repentance, now we have the treacherous enemy portrayed, and the saints in their helpless exposure suffering, but delivered by the destruction that falls on the Edomite at the end, when good shall flourish like the olive and give thanks forever.
