Some of you "greatly err, not knowing the scriptures". It is not unlawful for a Jew to lend money for usury in all circumstances, it is only unlawful to lend money for usury to fellow Jews. Reference Exodus 22:25 and Deuteronomy 23:20. These clearly spell out the Mosaic laws for usury. "Giving the money to the changers" would be a reference to the money changers in the Temple who would exchange foreign currency so that foreign worshippers could contribute to the Temple treasury. This was perfectly legal under Mosaic law. It started out as a legitimate enterprise but quickly became a get-rich-quick scam due to people's greed. These are the 'den or thieves' that Jesus chased out of the Temple, not because of their occupation, but because they used this occupation to rip off others.
How can some of you think this is a 'reverse parable' when it clearly starts out with the words "For the kingdom of heaven is as..." ? This describes the parable clearly as a comparison to the kingdom of heaven. Which part of that is backwards?
If you want the true meaning of the parable refer to James 1:5 "If any of you lack wisdom, let him ASK OF GOD, that giveth to all men liberally, and upbraideth not; and it shall be given him. " Prayer and meditation will be answered and you will find what the parable means TO YOU. True interpretation of Scripture will not be found in the commentaries of others. Each of us has a personal, individual, and unique spiritual walk. What this passage of Scripture means to you may be entirely different from the interpretation for me. Pray and meditate and get your personal interpretation directly from the one who will give you wisdom LIBERALLY.
