1 Samuel 18:1-5: in context

After David's victory over Goliath, the soul of Jonathan is knit to the soul of David, and Jonathan loves him as his own soul. The two make a covenant of friendship. And Jonathan does something remarkable: he strips off his own robe and gives it to David, along with his armor, his sword, his bow, and his belt. Jonathan, the king's son and heir to the throne, gives the tokens of his own royalty to the young man who, though neither yet says it, will one day reign in his place.

Jonathan's love for David is one of the moving friendships of Scripture, and what makes it so is its self-giving generosity. Jonathan loved David as his own soul, and his love took the form of giving: he stripped off his own robe and armor, the marks of his princely status, and put them on David. Consider what this meant. Jonathan was the crown prince, the natural heir; David was the rising figure who would take the throne that would otherwise have been Jonathan's. If anyone had reason to envy David, to guard his own position against him, it was Jonathan. Instead he loved him, gave to him, and later would actively help David toward the throne that Jonathan himself was giving up. His was a love free of envy, that sought David's good even at cost to his own standing. This is a rare and beautiful thing, and a challenging one. So much of our failure to love others generously comes from a kind of rivalry, the sense that another's rise is our loss, that to give to them or rejoice in them is to diminish ourselves. Jonathan shows a love that has broken free of that rivalry: he could give David his own robe, help him toward his own throne, and rejoice in it, because he loved David more than he loved his own position. To love like Jonathan is to be freed from envy, to seek the good of others, to give generously to them, even to rejoice in their rise, without the gnawing sense that their gain is our loss. It is the love that gives its own robe away.

Is my love for others shadowed by rivalry, the sense that their rise is my loss, so that I hold back from giving to them or rejoicing in them, or can I love as Jonathan loved David, freely and without envy, giving generously and seeking their good even at some cost to my own standing?
