1 Samuel 20:15

15 and do not ever cut off your loving devotion from my household—not even when the LORD cuts off every one of David’s enemies 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 bring evil on you, then may the LORD punish me, and ever so severely, if I do not tell you and send you on your way in safety. May the LORD be with you, just as He has been with my father.

14 And as long as I live, treat me with the LORD’s loving devotion, that I may not die,

15 and do not ever cut off your loving devotion from my household—not even when the LORD cuts off every one of David’s enemies from the face of the earth.”

16 So Jonathan made a covenant with the house of David, saying, “May the LORD hold David’s enemies accountable.”

17 And Jonathan had David reaffirm his vow out of love for him, for Jonathan loved David as he loved himself.
