This is a great Section for missionary work. V4 Talks about How the Lord "shall make up my jewels". According to my last scripture study this means, "The Great Men of The Lord" If we never have any gifts given to us by the lord taken away from us by the lord then we will become great men. The promise the Lord gives us in V2 says that if we do not preach the gospel because of fear the lord will take away what we have (Blessings received by the Gospel). V13 Do not idle away thy time, neither bury thy talent that it may not be known.
