Isaiah 1:23

Thy princes are rebellious, and companions of thieves: every one loveth gifts, and followeth after rewards: they judge not the fatherless, neither doth the cause of the widow come unto them.

Thy princes are rebellious,.... Stubborn and obstinate, refused to receive and acknowledge the Messiah; such were the Jewish rulers, civil and ecclesiastical, in the times of Christ.

and companions of thieves: who devoured widows' houses; made the temple, which was a house of prayer, a den of thieves; and took away the key of knowledge from the people, and would not suffer them to attend the ministry of the Gospel, Matthew 21:13

everyone loveth gifts, and followeth after rewards. The Targum paraphrases it,

"everyone says to his neighbour, do me a favour in my cause, I will return "it" to thee in thy cause;''

and so justice was perverted:

they judge not the fatherless; that is, either they do not take their cause in hand at all, or, if they do, do not do them justice, but wrong them of their goods and estates, which, of right, belong to them:

neither doth the cause of the widow come unto them; there being no money to be got by undertaking it; see the case of the unjust judge, a picture of judges in those times, Luke 18:2.
