John Gill Commentary Psalms 26:10

"In whose hands is wickedness, And their right hand is full of bribes." — Psalms 26:10 (ASV)

In whose hands [is] mischief
Every abominable wickedness; as idolatry, adultery, murder the word signifies and is sometimes used for mischief conceived in the mind, artificially devised and contrived there; here mischief committed, the hand being the instrument of action, and intends whatever is prejudicial to the person, character, and properties of men;

and their right hand is full of bribes ;
whereby the eyes of judges are blinded, the words of the righteous perverted, men's persons respected, and judgment wrested, (Deuteronomy 16:19) .
