Matthew 5:4.
Tyndale's translations

With each beatitude the gulf is widened between the disciples and the people, their call to come forth from the people becomes increasingly manifest. By “mourning” Jesus, of course, means doing without what the world calls peace and prosperity: He means refusing to be in tune with the world or to accommodate oneself to its standards. Such men mourn for the world, for its guilt, its fate, and its fortune.

1850s, Speech at Peoria, Illinois (1854)
Context: Our republican robe is soiled, and trailed in the dust. Let us repurify it. Let us turn and wash it white, in the spirit, if not the blood, of the Revolution. Let us turn slavery from its claims of “moral right,” back upon its existing legal rights, and its arguments of 'necessity'. Let us return it to the position our fathers gave it; and there let it rest in peace. Let us re-adopt the Declaration of Independence, and with it, the practices, and policy, which harmonize with it. Let north and south — let all Americans — let all lovers of liberty everywhere — join in the great and good work. If we do this, we shall not only have saved the Union; but we shall have so saved it, as to make, and to keep it, forever worthy of the saving. We shall have so saved it, that the succeeding millions of free happy people, the world over, shall rise up, and call us blessed, to the latest generations.
