Charles Ellicott Commentary James 3:16

"For where jealousy and faction are, there is confusion and every vile deed." — James 3:16 (ASV)

For where envying and strife is, there is confusion.—Where emulation, zeal, and rivalry exist, there also are sedition, anarchy, restless disturbance, and every villainous act. The whole state is evil, and utterly contrary to the rule of the Gospel—

“For words and names let angry zealots fight:
Whose life is in the wrong can never be right.”
