Psalms 64:6

They search out iniquities
The Targum adds,

``to destroy the just.''

Either occasions against them, by charging them with sin and hiring false witnesses against them, as did the enemies both of David and Christ; they sought for proper time and opportunity of committing the iniquities they were bent upon, and even searched for new sins, being inventors of evil things, ( Romans 1:30 ) ;

they accomplish a diligent search;
diligently searched out the perfect man, and found him; and also false witnesses against him, and carried their point; which was especially true with respect to Christ;

both the inward [thought] of everyone [of them], and the heart, [is]
deep;
being full of cunning, craftiness and wickedness, so as not to be searched out and fully known; see ( Psalms 5:9 ) ( Jeremiah 17:9 ) .
