Thematic Bible: David was false to joab

Moreover also, thou, knowest what Joab son of Zeruiah did to me, how he dealt with two generals of the armies of Israel - with Abner son of Ner, and with Amasa son of Jether - both of whom he slew, shedding the blood of war in peace, - and putting the blood of war upon his girdle that was on his loins, and upon his sandals, that were on his feet. Thou, therefore, must do according to thy wisdom, - but will not let his grey hair go down in peace, to hades.
