1 Samuel - Chapter 20

In this chapter Jonathan has to choose between David and his father Saul.  He chooses David:

"Jonathan said to David, ‘Go in peace, for we have sworn friendship with each other in the name of the Lord, saying, “The Lord is witness between you and me, and between your descendants and my descendants for ever.”’ Then David left, and Jonathan went back to the town."

Jesus tells his followers that they, too, must make this choice:

Large crowds were travelling with Jesus, and turning to them he said: ‘If anyone comes to me and does not hate father and mother, wife and children, brothers and sisters – yes, even their own life – such a person cannot be my disciple. And whoever does not carry their cross and follow me cannot be my disciple.
