1 Samuel 18:2-4

New Revised Standard Version, Anglicised Catholic Edition

² Saul took him that day and would not let him return to his father’s house. ³ Then Jonathan made a covenant with David, because he loved him as his own soul. ⁴ Jonathan stripped himself of the robe that he was wearing, and gave it to David, and his armour, and even his sword and his bow and his belt.
