1 Samuel 18:1

A man that hath friends must shew himself friendly: and there is a friend that sticketh closer than a brother.

And Jonathan caused David to swear again, because he loved him: for he loved him as he loved his own soul.

Then Jonathan and David made a covenant, because he loved him as his own soul.

I am distressed for thee, my brother Jonathan: very pleasant hast thou been unto me: thy love to me was wonderful, passing the love of women.

That their hearts might be comforted, being knit together in love, and unto all riches of the full assurance of understanding, to the acknowledgement of the mystery of God, and of the Father, and of Christ;

Now therefore when I come to thy servant my father, and the lad be not with us; seeing that his life is bound up in the lad’s life;

If thy brother, the son of thy mother, or thy son, or thy daughter, or the wife of thy bosom, or thy friend, which is as thine own soul, entice thee secretly, saying, Let us go and serve other gods, which thou hast not known, thou, nor thy fathers;

But 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:

And David went out to meet them, and answered and said unto them, If ye be come peaceably unto me to help me, mine heart shall be knit unto you: but if ye be come to betray me to mine enemies, seeing there is no wrong in mine hands, the God of our fathers look thereon, and rebuke it.

So all the men of Israel were gathered against the city, knit together as one man.

And the people said unto Saul, Shall Jonathan die, who hath wrought this great salvation in Israel? God forbid: as the LORD liveth, there shall not one hair of his head fall to the ground; for he hath wrought with God this day. So the people rescued Jonathan, that he died not.

Teach me thy way, O LORD; I will walk in thy truth: unite my heart to fear thy name.
