Psalms 109:6 Set thou a wicked man over him: and let Satan stand at his right hand. 7 When he shall be judged, let him be condemned: and let his prayer become sin.
Luke 22:1 Now the feast of unleavened bread drew nigh, which is called the Passover. 2 And the chief priests and scribes sought how they might kill him; for they feared the people. 3 Then entered Satan into Judas surnamed Iscariot, being of the number of the twelve. 4 And he went his way, and communed with the chief priests and captains, how he might betray him unto them.
Psalms 109:8 Let his days be few, (That is because Judas’ days would be cut short by suicide) and let another take his office. 9 Let his children be fatherless, and his wife a widow. {All references to Judas’ death by suicide}
Matthew 27: 3 Then Judas, which had betrayed him, when he saw that he was condemned, repented himself, and brought again the thirty pieces of silver to the chief priests and elders, 4 Saying, I have sinned in that I have betrayed the innocent blood. And they said, What is that to us? see thou to that. 5 And he cast down the pieces of silver in the temple, and departed, and went and hanged himself.
Obviously, an entirely different picture is beginning to emerge, because it is evident that David was not the focus of these passages, nor are his words some off the cuff rant, against some unknown individual, because of him drooling over personal revenge.
2nd Peter 1: 19 We have also a more-sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts. 20 Knowing this first, that no prophecy of the scripture is of any private interpretation. 21 For the prophecy came not in old time by the will of man: but holy men of God spoke as they were moved by the Holy Ghost.
May The Lord add His blessing to the study of His word. God bless!
