If I do not remember you, let my tongue cleave to the roof of my mouth; if I prefer not Jerusalem above my chief joy.
Read Chapter 137
Augustine of Hippo
9. "Let my tongue cleave to my jaws, if I remember not thee" (ver. 6). That is, let me be dumb, he saith, if I remember not thee. For what word, what sound doth he utter, who uttereth not songs of Sion? That is our tongue, the song of Jerusalem. The song of the love of this world is a strange tongue, a barbarous tongue, which we have learnt in our captivity. Dumb then will he be to God, who forgetteth Jerusalem. And it is not enough to remember: for her enemies too remember her, desiring to overthrow her. "What is that city?" say they; "who are the Christians? what sort of men are the Christians? would they were not Christians." Now the captive band hath conquered its capturers; still they murmur, and rage, and desire to slay the holy city that dwells as a stranger among them. Not enough then is it to remember: take heed how thou rememberest. For some things we remember in hate, some in love. And so, when he had said, "If I forget thee, O Jerusalem," etc., he added at once, "if I prefer not Jerusalem in the height of my joy." For there is the height of joy where we enjoy God, where we are safe of united brotherhood, and the union of citizenship. There no tempter shall assail us, no one be able so much as to urge us on to any allurement: there nought will delight us but good: there all want will die, there perfect bliss will dawn on us.
