Went before. — Translate, met. (Comp. Note on 2 Samuel 19:6.)
As he went forth it fell out. — The object of this verse is to explain how Joab, in consequence of the arrangement of his dress, was able to stab Amasa without his purpose being suspected. He had a girdle bound round his military coat, and in this he had stuck a dagger so arranged that it might fall out as he advanced. He then picked this up naturally in his left hand, and stretching out his right hand to greet Amasa, his movements gave rise to no suspicion.
