Then Jonathan said to the young man who was carrying his armor, "Come and let us cross over to the garrison of these uncircumcised; perhaps the LORD will work for us, for the LORD is not restrained to save by many or by few."
Then David spoke to the men who were standing by him, saying, "What will be done for the man who kills this Philistine and takes away the reproach from Israel? For who is this uncircumcised Philistine, that he should taunt the armies of the living God?"
"Your servant has killed both the lion and the bear; and this uncircumcised Philistine will be like one of them, since he has taunted the armies of the living God."
Then Saul said to his armor bearer, "Draw your sword and pierce me through with it, otherwise these uncircumcised will come and pierce me through and make sport of me." But his armor bearer would not, for he was greatly afraid. So Saul took his sword and fell on it.
