The link was given in response to your inference that Jefferson was a hypocrite, not to validate slavery using the OT or otherwise.
The Founders Believed Slavery Was Fundamentally Wrong.
"Thomas Jefferson's original draft of the Declaration included a strong denunciation of slavery, declaring the king's perpetuation of the slave trade and his vetoing of colonial anti-slavery measures as one reason the colonists were declaring their independence:
He [King George III] has waged cruel war against human nature itself, violating its most sacred rights of life and liberty in the persons of a distant people who never offended him, captivating and carrying them into slavery in another hemisphere. . . . Determined to keep open a market where MEN should be bought and sold, he has prostituted his negative for suppressing every legislative attempt to prohibit or restrain this execrable commerce. 22 "
The Founders took action against slavery.
There is no question Jefferson was a hypocrite, and I was not inferring it. I was stating it, and I think it’s so obvious the statement doesn’t really need any defense. What would YOU call someone who proclaims his hatred of slavery while simultaneously owning 200 human beings, and routinely selling off one or two whenever he wants some new furniture?
It is also fair to say there are reasons why he and others of his time were forced into a hypocritical position. And their hypocrisy was far preferable to the position many of their grandsons took of proclaiming slavery to be a positive good, working aggressively for its perpetuation and extension.
I have read perhaps a half dozen biographies each of Jefferson, Washington and Adams.
The more I learn about Washington and Adams, the greater my admiration for them, although frankly Adams got a little odd in his later years politically.
The more I learn about Jefferson the more I become aware of his hypocrisy, manipulativeness, cowardice and other unattractive traits.
He wrote the most magnificent rhetoric in all history in the cause of liberty. He was also pretty much of a dishonorable jerk. The former far outweighs the latter in the eyes of history, as it should, but as a man he falls far below the other two.
BTW, I recognize I was unclear in my comments on the OT and slavery. I wasn’t trying to say you were trying to justify slavery on this basis, but doing so was very common among defenders of slavery in the 19th century.
