1 Samuel 18:1

Y ASÍ que él hubo acabado de hablar con Saúl, el alma de Jonathán fué ligada con la de David, y amólo Jonathán como á su alma.

And it came to pass, when he had made an end of speaking unto Saul, that the soul of Jonathan was knit with the soul of David, and Jonathan loved him as his own soul.
