Flat's position is that learning foreign languages is evil.
From a logical point of view, FLAT should be advocating that we speak only Hebrew!
The scripture is
Tower of Babel Gen 11:1-9
7 "Come, let us go down and confuse their language so they will not understand each other."
God gave us "foreign languages." So FLAT is saying that God gave us an eveil thing.
No where in this passage does God say don't speak another language. No where is the Bible does God say don't speak another language. In fact, the Jews spoke several. Although they got in trouble with God for a number of things, speaking foreign languages was not one of them.
