Moravian slaves

The Moravian Slaves, a popular narrative about Christian Missions concerning Johann Leonhard Dober and David Nitschmann, describes how these two young Moravian Brethren from Herrnhut, Germany, were called in 1732 to minister to the African slaves on the islands of St. Thomas and St. Croix in the Danish West Indies. Allegedly, when they were told that they would not be allowed to do such a thing, Dober and Nitschmann sold themselves to a slave owner and boarded a ship bound for the West Indies. As the ship pulled away from the docks, it is said that they called out to their loved ones on shore, "May the Lamb that was slain receive the reward of His suffering!"
