Jamieson, Fausset and Brown on James 2:6

6. The world's judgment of the poor contrasted with God's.

ye--Christians, from whom better things might have been expected; there is no marvel that men of the world do so.

despised--literally, "dishonored." To dishonor the poor is to dishonor those whom God honors, and so to invert the order of God [Calvin].

rich--as a class.

oppress--literally, "abuse their power against" you.

draw you--Translate, "is it not they (those very persons whom ye partially prefer, Jas 2:1-4) that drag you (namely, with violence)" [Alford].

before ... judgment seats--instituting persecutions for religion, as well as oppressive lawsuits, against you.
