1 Samuel 20:15

15 never cut off your faithful love from my house, even if the Lord were to cut off every one of the enemies of David from the face of the earth."

1 Samuel 20:15 Meaning and Commentary

1 Samuel 20:15

But also thou shalt not cut off thy kindness from my house
for ever
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.

1 Samuel 20:15 In-Context

13 But if my father intends to do you harm, the Lord do so to Jonathan, and more also, if I do not disclose it to you, and send you away, so that you may go in safety. May the Lord be with you, as he has been with my father.
14 If I am still alive, show me the faithful love of the Lord; but if I die,
15 never cut off your faithful love from my house, even if the Lord were to cut off every one of the enemies of David from the face of the earth."
16 Thus Jonathan made a covenant with the house of David, saying, "May the Lord seek out the enemies of David."
17 Jonathan made David swear again by his love for him; for he loved him as he loved his own life.
