10 Day and night they go about it upon the walls thereof: mischief also and sorrow are in the midst of it.
10 Day and night they prowl about on its walls; malice and abuse are within it.
10 Day and night they go around it on its walls, and iniquity and trouble are within it;
10 Day and night spoiling for a fight, trash piled in the streets,
10 Day and night they go around it on its walls; Iniquity and trouble are also in the midst of it.
10 Its walls are patrolled day and night against invaders, but the real danger is wickedness within the city.
Matthew Henry's Commentary on Psalm 55:10
Commentary on Psalm 55:9-15
(Read Psalm 55:9-15)
No wickedness so distresses the believer, as that which he witnesses in those who profess to be of the church of God. Let us not be surprised at the corruptions and disorders of the church on earth, but long to see the New Jerusalem. He complains of one that had been very industrious against him. God often destroys the enemies of the church by dividing them. And an interest divided against itself cannot long stand. The true Christian must expect trials from professed friends, from those with whom he has been united; this will be very painful; but by looking unto Jesus we shall be enabled to bear it. Christ was betrayed by a companion, a disciple, an apostle, who resembled Ahithophel in his crimes and doom. Both were speedily overtaken by Divine vengeance. And this prayer is a prophecy of the utter, the everlasting ruin, of all who oppose and rebel against the Messiah.
