John Wesley on 2 Samuel 3:34

Not bound - Thou didst not tamely yield up thyself to Joab, to be bound hand and foot at his pleasure. Joab did not overcome thee in an equal combat, nor durst he attempt thee in that way, as a general or soldier of any worth would have done. Wicked men - By the hands of froward, or perverse, or crooked men, by hypocrisy and perfidiousness, whereby the vilest coward may kill the most valiant person.
