1 Samuel 19:3 KJV

1And Saul spake to Jonathan his son, and to all his servants, that they should kill David.

2But Jonathan Saul’s son delighted much in David: and Jonathan told David, saying, Saul my father seeketh to kill thee: now therefore, I pray thee, take heed to thyself until the morning, and abide in a secret place, and hide thyself:

3And I will go out and stand beside my father in the field where thou art, and I will commune with my father of thee; and what I see, that I will tell thee.

4And Jonathan spake good of David unto Saul his father, and said unto him, Let not the king sin against his servant, against David; because he hath not sinned against thee, and because his works have been to thee-ward very good:

5For he did put his life in his hand, and slew the Philistine, and the LORD wrought a great salvation for all Israel: thou sawest it, and didst rejoice: wherefore then wilt thou sin against innocent blood, to slay David without a cause?
