Billboards with the Ten Commandments are a great idea. But one important consideration should be that King James English was great for King James' time. Today's common reader may not warm to "thou shalt." Also, another important consideration is that the sixth commandment should be explained today in terms of "You shall not commit murder." The Lord commanded the Israelis to execute the perverse from their land, as well as for governments (and their police/militaries) to bear the "sword" against those intent upon hurting the innocent.
