1 Samuel 17:47

17:47 and all this assembly will know that it is not by sword or spear that the Lord saves! For the battle is the Lord’s, and he will deliver you into our hand.”

1 Samuel 17:2

1 Samuel 20:15-17

20:15 Don’t ever cut off your loyalty to my family, not even when the Lord has cut off every one of David’s enemies from the face of the earth 20:16 and called David’s enemies to account.” So Jonathan made a covenant with the house of David. 20:17 Jonathan once again took an oath with David, because he loved him. In fact Jonathan loved him as much as he did his own life.
