1 Samuel 20:14

¹²  And Jonathan said unto David, O LORD God of Israel, when I have sounded my father about to morrow any time, or the third day, and, behold, if there be good toward David, and I then send not unto thee, and show it thee;

¹³  The LORD do so and much more to Jonathan: but if it please my father to do thee evil, then I will show it thee, and send thee away, that thou mayest go in peace: and the LORD be with thee, as he hath been with my father.

¹⁴  And thou shalt not only while yet I live show me the kindness of the LORD, that I die not:

¹⁵  But also thou shalt not cut off thy kindness from my house for ever: no, not when the LORD hath cut off the enemies of David every one from the face of the earth.

¹⁶  So Jonathan made a covenant with the house of David, saying, Let the LORD even require it at the hand of David's enemies.
