Psalms 63:9

"But themselves in vain have sought my soul. They shall go unto the lower places of the earth." Earth they were unwilling to lose, when they crucified Christ: into the lower places of the earth they have gone. What are the lower places of the earth? Earthly lusts. Better it is to walk upon earth, than by lust to go under earth. For every one that in prejudice of his salvation desireth earthly things, is under the earth: because earth he hath put before him, earth upon himself he hath put, and himself beneath he hath laid. They therefore fearing to lose earth, said what of the Lord Jesus Christ, when they saw great multitudes go after Him, forasmuch as He was doing wonderful things? "If we shall have let Him go alive, there will come the Romans, and will take away from us both place and nation." They feared to lose earth, and they went under the earth: there befell them even what they feared. For they willed to kill Christ, that they might not lose earth; and earth they therefore lost, because Christ they slew. For when Christ had been slain, because the Lord Himself had said to them, "The kingdom shall be taken from you, and shall be given up to a nation doing righteousness:" there followed them great calamities of persecutions: there conquered them Roman emperors, and kings of the nations: they were shut out from that very place where they crucified Christ, and now that place is full of Christian praisers: it hath no Jew, it hath been cleared of the enemies of Christ, it hath been fulfilled with the praisers of Christ. Behold, they have lost at the hands of the Romans the place, because Christ they slew, who to this end slew, that they might not lose the place at the hands of the Romans. Therefore, "They shall enter into the lower places of the earth."

They shall die a violent death, Rev. xiii. This was fulfilled in Saul, who fell by the sword, his own sword; David foretold this, yet he would not execute it when it was in the power of his hand, once and again; for precepts, not prophecies, are our rule.

As David earnestly sought for God, so there were men of another order who as eagerly sought after his blood; of these he speaks: But those that seek my soul, to destroy it. At his life they aimed, at his honour, his best welfare; and this they would not merely injure but utterly ruin. The devil is a destroyer, and all his seed are greedy to do the same mischief; and as he has ruined himself by his crafty devices, so also shall they. Destroyers shall be destroyed. Those who hunt souls shall be themselves the victims.

Those who hunt souls shall be themselves the victims. Shall go into the lower parts of the earth. Into the pits which they digged for others they shall fall themselves. The slayers shall be slain, and the grave shall cover them. The hell which they in their curse invoked for others shall shut its mouth upon them. Every blow aimed against the godly will recoil on the persecutor; he who smites a believer drives a nail in his own coffin.

Lower parts of the earth - They are appointed, in the just judgment of God, to destruction; they shall be slain and buried in the earth, and shall be seen no more. Some understand the passage as referring to the punishment of hell; which many supposed to be in the center of the earth. So the old Psalter, - Thai sall entir in till lagher pine of hell. Lahher or laigher, lower, undermost.
