The first revenue is the tithe. It should be collected as follows: If, for instance, the income of a person is five hundred dollars and his necessary expenses are the same, no tithes will be collected from him. If another’s expenses are five hundred dollars while his income is one thousand dollars, one tenth will be taken from him, for he hath more than his needs; if he giveth one tenth of the surplus, his livelihood will not be adversely affected. If another’s expenses are one thousand dollars, and his income is five thousand dollars, as he hath four thousand dollars surplus he will be required to give one and a half tenths. If another person hath necessary expenses of one thousand dollars, but his income is ten thousand dollars, from him two tenths will be required for his surplus represents a large sum. But if the necessary expenses of another person are four or five thousand dollars, and his income one hundred thousand, one fourth will be required from him. On the other hand, should a person’s income be two hundred, but his needs absolutely essential for his livelihood be five hundred dollars, and provided he hath not been remiss in his work or his farm hath not been blessed with a harvest, such a one must receive help from the general storehouse so that he may not remain in need and may live in comfort.
