13.17.21   But the souls that thirst after Thee, and that appear before Thee (being by other bounds divided from the society of the sea), Thou waterest by a sweet spring, that the earth may bring forth her fruit, and Thou, Lord God, so commanding, our soul may bud forth works of mercy according to their kind, loving our neighbour in the relief of his bodily necessities, having seed in itself according to its likeness, when from feeling of our infirmity, we compassionate so as to relieve the needy; helping them, as we would be helped; if we were in like need; not only in things easy, as in herb yielding seed, but also in the protection of our assistance, with our best strength, like the tree yielding fruit: that is, well-doing in rescuing him that suffers wrong, from the hand of the powerful, and giving him the shelter of protection, by the mighty strength of just judgment.
