As David returned from the slaughter of the Philistine, Abner took him, and brought him before Saul with the head of the Philistine in his hand.
And daily he would challenge them. He would say, "Look facing off here in battle. We can settle it easily. Send out a man to fight me, for I'm a Philistine, you're the Israelites, and if you've got a man in your army that's able to fight me, if he can defeat me, we'll be your servants. If I can beat him, then you'll be our servants." He was daily challenging them for forty days.
