Augustine, Confessions §aug_conf_09_002: And I resolved in Thy sight, not tumultuously to tear, but gently to withdraw...

And I resolved in Thy sight, not tumultuously to tear, but gently to withdraw, the service of my tongue from the marts of lip-labour: that the young, no students in Thy law, nor in Thy peace, but in lying dotages and law-skirmishes, should no longer buy at my mouth arms for their madness. And very seasonably, it now wanted but very few days unto the Vacation of the Vintage, and I resolved to endure them, then in a regular way to take my leave, and having been purchased by Thee, no more to return for sale. Our purpose then was known to Thee; but to men, other than our own friends, was it not known. For we had agreed among ourselves not to let it out abroad to any: although to us, now ascending from the valley of tears, and singing that song of degrees, Thou hadst given sharp arrows, and destroying coals against the subtle tongue, which as though advising for us, would thwart, and would out of love devour us, as it doth its meat.
