"Because the assumption of Mosaic ethnology was well established, it was important to secure both families of languages within that framework. Ellis claimed that Tamil is connected with Hebrew and also with ancient Arabic. Their logic was that since William Jones considered Sanskrit to be the language of Ham, and other scholars claimed that Sanskrit descended from Noah's oldest son, Japheth, by the process of elimination the remaining son of Noah, Shem, must be the ancestor of the Dravidian people. This made Dravidians a branch of the Scythians or in the same family as Jews."
