1 Samuel 20:15

15 And never stop being kind to my family. Don't stop even when the LORD has cut off every one of your 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 suppose he wants to harm you. And I don't let you know about it. I don't help you get away safely. Then may the LORD punish me greatly. May he be with you, just as he has been with my father.

14 "But always be kind to me, just as the LORD is. Be kind to me as long as I live. Then I won't be killed.

15 And never stop being kind to my family. Don't stop even when the LORD has cut off every one of your enemies from the face of the earth."

16 So Jonathan made a covenant with David and his family. He said, "May the LORD make David's enemies accountable for what they've done."

17 Jonathan had David take an oath again because he loved him. In fact, Jonathan loved David just as he loved himself.
