SEV Biblia, Chapter 20:15
no quitarás perpetuamente tu misericordia de mi casa. Cuando desarraigare el SEÑOR uno por uno los enemigos de David de la tierra, aun a Jonatán quite de su casa, si te faltare ; y requiera el SEÑOR de la mano de los enemigos de David.
John Gill's Bible Commentary
Ver. 15. But also thou shalt not cut off thy kindness from my house for ever , etc.] His family should partake of it as well as himself: no, not when the Lord hath cut off the enemies of David, everyone from the face of the earth ; Saul and his sons, and everyone that should oppose his settlement in the kingdom: Jonathan’s meaning is, that the covenant between them should not be only between them personally, but include their posterity, as follows.
Matthew Henry Commentary
Verses 11-23 - Jonathan faithfully promises that he would let David know how he foun his father affected towards him. It will be kindness to ourselves an to ours, to secure an interest in those whom God favours, and to make his friends ours. True friendship rests on a firm basis, and is able to silence ambition, self-love, and undue regard for others. But who can fully understand the love of Jesus, who gave himself as a sacrifice for rebellious, polluted sinners! how great then ought to be the force an effects of our love to him, to his cause, and his people!
