The idea underlying the outbreak at Harper’s Ferry is not peculiar to that movement, but dates back to a period very far beyond the memory of the “oldest inhabitant,” and emanated from a source much superior to the Wises and Hunters, the Buchanans and Masons of to-day. It was the appointed work for life of an ancient patriarch spoken of in Exodus, chap, ii., and who, true to his great commission, failed not to trouble the conscience and to disturb the repose of the Pharaohs of Egypt with that inexorable, “Thus saith the Lord: Let my people go!” until even they were urgent upon the people in its behalf. Coming down through the nations, and regardless of national boundaries or peculiarities, it has been proclaimed and enforced by the patriarch and the warrior of the Old World, by the enfranchised freeman and the humble slave of the New. Its nationality is universal; its language every where understood by the haters of tyranny; and those that accept its mission, every where understand each other. There is an unbroken chain of sentiment and purpose from Moses of the Jews to John Brown of America; from Kossuth, and the liberators of France and Italy, to the untutored Gabriel, and the Denmark Veseys, Nat Turners and Madison Washingtons of the Southern American States. The shaping and expressing of a thought for freedom takes the same consistence with the colored American--whether he be an independent citizen of the Haytian nation, a proscribed but humble nominally free colored man, a patient, toiling, but hopeful slave--as with the proudest or noblest representative of European or American civilization and Christianity. Lafayette, the exponent of French honor and political integrity, and John Brown, foremost among the men of the New World in high moral and religious principle and magnanimous bravery, embrace as brothers of the same mother, in harmony upon the grand mission of liberty; but, while the Frenchman entered the lists in obedience to a desire to aid, and by invitation from the Adamses and Hamiltons, and thus pushed on the political fortunes of those able to help themselves, John Brown, the liberator of Kansas, the projector and commander of the Harper’s Ferry expedition, saw in the most degraded slave a man and a brother, whose appeal for his God-ordained rights no one should disregard; in the toddling slave child, a captive whose release is as imperative, and whose prerogative is as weighty, as the most famous in the land. When the Egyptian pressed hard upon the Hebrew, Moses slew him; and when the spirit of slavery invaded the fair Territory of Kansas, causing the Free-State settlers to cry out because of persecution, old John Brown, famous among the men of God for ever, though then but little known to his fellow-men, called together his sons and went over, as did Abraham, to the unequal contest, but on the side of the oppressed white men of Kansas that were, and the black men that were to be.
