Leviticus 27 is not really a way to get out of your vow to the Lord. It’s a reminder to not make hasty vows that you can’t or have no intention of honoring. There is cost and sometimes a penalty that must be paid.
Much has been made about tithing, but there is something here that isn’t often talked about. The temple dealt in commodities that could be used immediately. If you brought money instead of grain, that was inconvenient, because it would have to be turned into a commodity. So a “tithe” of money instead of grain became 12%!
Thought for the day: Jesus warns us about the misuse of vows and the importance of truthfulness:
Matthew 5:33-37 (WEB) ” ‘Again you have heard that it was said to the ancient ones, “You shall not make false vows, but shall perform to the Lord your vows,” but I tell you, don’t swear at all: neither by heaven, for it is the throne of God; nor by the earth, for it is the footstool of his feet; nor by Jerusalem, for it is the city of the great King. Neither shall you swear by your head, for you can’t make one hair white or black. But let your “Yes’” be “Yes” and your “No” be “No.” Whatever is more than these is of the evil one.’ “
