The conclusion of the whole matter is this: It is clear that according to all tradition in Israel, tablets of gold and of brass were kept, inscribed with holy writings from antiquity far antedating Moses, and thereafter. It is clear that Israel stood on no basis different from her neighbors in the use of metals or in culture. These neighbors utilized brass plates for many centuries and set their permanent records upon them many times. The history of Israel outside the scriptures attest the making and use of such records in Israel. In the scriptures the knowledge o the use of brass and other brilliant metal plates and the existence of a high skill in engraving words upon them is demonstrated. Among the prophets there is direct evidence that by commandment of God the words of prophecy were cut in imperishable letters upon such plates for the time to come, forever.
