11 Saul also sent messengers unto David's house, to watch him, and to slay him in the morning: and Michal David's wife told him, saying, If thou save not thy life to night, to morrow thou shalt be slain.
The story relates how, when the vehement emotion of the demonic spirit had settled on Saul and the holy David quieted the disturbance of the passion by means of his psaltery, Saul found the spear that was standing by him, aimed it straight at David and hurled it against his benefactor. David, however, avoided the attack on himself by means of the divine alliance, and the assault of the spear fixed itself deeply in the wall. He fled the royal dwellings and was in his own house, in the hope that repentance would alter the king’s anger. But Saul placed his spearmen around David’s house and ordered the executioners to kill him. He barely escaped the dangers by letting himself down into the open through a window and avoiding detection by the guard.
“Then Saul sent and watched his house to kill him.” This too is fittingly associated with the Lord’s passion, for house indicates the tomb where he rested in a three-day death. The Jews’ leaders sent men to guard it, to destroy so to say the fame of his name, so that by some trick it should not be claimed that he rose again, an eventuality which Christ had been heard earlier proclaiming. It was better that his enemies should of their own accord desire to condemn this, for it allowed the whole world to acknowledge the fact more certainly. The evidence which the unwilling witness offers is beyond doubt; it cannot be called partisan when confirmed by the guilty person.
Therefore Saul sent his messengers to David's house, etc. The chief priests and Pharisees sent their messengers to the Lord's tomb to guard it, hoping that by denying the truth of the resurrection, the memory of His name would be erased in the future. The frequent laments of the Church announced this to Him (for the Lord hears the desire of the poor [Psalm IX]), and trembling from the conspiracy of the faithless, it somehow said: Unless you rise from the dead, the faith and confession of the believers in you cannot firmly persist; unless you invalidate the watchfulness of the guards by overcoming death, the whole faith in the future resurrection will be taken away from the world; at last, it learned that He had left the tomb's location to His guards. He went away and escaped from His executioners and the lying guards; and by appearing to His dear ones after the resurrection, He completely restored their hope and faith. David's harp can specifically and figuratively represent the cross of the Lord; Saul's spear on the wall can represent the nails of the cross, or the very soldier's lance which opened His side. As we have said, David's house is the tomb of the Lord. The leap through the window is the concealed and sudden speed of the resurrection. The wife from whom he escaped through a plan is the Church of believing Jews, who both desired the Lord Savior to rise and taught that He had risen.
