[bbe] Everyone says false words to his neighbour: their tongues are smooth in their talk, and their hearts are full of deceit.

European/American slavery, 17th and 18th centuries[edit]
The explanation that black Africans, as the "sons of Ham", were cursed, possibly "blackened" by their sins, was advanced only sporadically during the Middle Ages, but it became increasingly common during the slave trade of the 18th and 19th centuries.[58][59] The justification of slavery itself through the sins of Ham was well suited to the ideological interests of the elite; with the emergence of the slave trade, its racialized version justified the exploitation of African labour.
At some point after the slave trade in the U.S. began, many protestant denominations began teaching that the mark of Cain was black skin. This was commonly accepted as late as the early 20th century by the vast majority of Christians, even those being black, progressive, and seeking full equality. Protestant preachers were writing exegetical analyses of the curse, with the assumption it was black skin.[20]
