Near eighty years ago we began by declaring that all men are created equal; but now from that beginning we have run down to the other declaration, that for some men to enslave others is a “sacred right of self-government.” These principles can not stand together. They are as opposite as God and mammon; and whoever holds to the one, must despise the other.

Speaking on the 1854 Kansas-Nebraska Act, which repealed the Missouri Compromise and allowed as "self-government" for residents of those two territories to decide locally whether to allow slavery there.
Lincoln is referencing both the Declaration of Independence and the Bible (Luke 16:13).
