1 Samuel 17:8-53 And he stood and cried unto the armies of Israel, and said unto them, Why are ye come out to set your battle in array? am not I a Philistine, and ye servants to Saul? choose you a man for you, and let him come down to me. 9 If he be able to fight with me, and to kill me, then will we be your servants: but if I prevail against him, and kill him, then shall ye be our servants, and serve us. 10 And the Philistine said, I defy the armies of Israel this day; give me a man, that we may fight together. 11 When Saul and all Israel heard those words of the Philistine, they were dismayed, and greatly afraid. ...

2 Samuel 2:14-17 And Abner said to Joab, Let the young men now arise, and play before us. And Joab said, Let them arise. 15 Then there arose and went over by number twelve of Benjamin, which pertained to Ishbosheth the son of Saul, and twelve of the servants of David. 16 And they caught every one his fellow by the head, and thrust his sword in his fellow's side; so they fell down together: wherefore that place was called Helkathhazzurim, which is in Gibeon. 17 And there was a very sore battle that day; and Abner was beaten, and the men of Israel, before the servants of David.

2 Samuel 21:15-22 Moreover the Philistines had yet war again with Israel; and David went down, and his servants with him, and fought against the Philistines: and David waxed faint. 16 And Ishbibenob, which was of the sons of the giant, the weight of whose spear weighed three hundred shekels of brass in weight, he being girded with a new sword, thought to have slain David. 17 But Abishai the son of Zeruiah succoured him, and smote the Philistine, and killed him. Then the men of David sware unto him, saying, Thou shalt go no more out with us to battle, that thou quench not the light of Israel. 18 And it came to pass after this, that there was again a battle with the Philistines at Gob: then Sibbechai the Hushathite slew Saph, which was of the sons of the giant. ...
