“A man who bears false witness against his neighbor”: Revised Standard Version and Good News Translation reverse the Hebrew line order, placing the comparison in the second line. For “false witness” see 6.19, where the same Hebrew expression is used. To “bear false witness” means to lie as a court witness against a “neighbor”, which has the sense here of “companion” (New Jerusalem Bible) or “friend” (Revised English Bible, Contemporary English Version). See Exo 20.16, the ninth commandment, for a similar expression.

“Is like a war club, or a sword, or a sharp arrow”: Lying as a witness is compared with weapons of war, things that injure and kill people. “A war club” renders a term that means “that which shatters.” It is a weapon usually fashioned from a heavy stick or tree branch. The words “sword” and “arrow” are the names of other weapons. In translation it may be necessary to make clear the nature of the comparison, which Good News Translation calls “deadly as.” We may translate this saying, for example, “If you tell lies about someone, it is like attacking them with a war club, a sword, or with sharp arrows.”
