The text says that witnesses must be trustworthy. No one will be convicted on the word of just one witness. If someone testifies falsely against another man, then the priests and judges will rule between them, and the false witness will receive the punishment he intended for his brother. This way, evil will be put away from among the people. No pity for evil. This is a passage where the phrase, “an eye for an eye” comes in. Specifically,
Deuteronomy 19:21 (NKJV)
21 Your eye shall not pity: life shall be for life, eye for eye, tooth for tooth, hand for hand, foot for foot.
This passage discusses the modern word, “perjury.” False witnesses can be found guilty and held for undetermined amounts of time. While it is not a capital offense, it is considered serious and damaging to the American justice system. In true spiritual life, honesty is always the best, and the only acceptable policy for believers.
