1 Samuel 20:17

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

And Jonathan caused David to swear again, because he loved him: for he loved him as he loved his own soul.

Note because…: or, by his love toward him

Jonathan caused David to swear again, for the love that he had for him; for he loved him as he loved his own soul.

And Jonathan caused David to swear again, for the love that he had to him; for he loved him as he loved his own soul.
