Deuteronomy 9:3

The promise belongs to the extended instruction found in Deuteronomy chapters four through eleven, and that whole portion is needed to understand God's dealings with His people. That instruction is not confined to ancient Israel, for it applies directly to those carrying responsibilities in sanitarium work. Every direction God gives in those chapters is therefore binding, from the greatest requirement to what may seem the least. All of it is to be carefully observed by workers entrusted with such responsibilities.
