We live in a culture that sees little problem with bending the truth. On the surface they may not be telling a down right lie but neither is it the whole truth. It may be several shades of the truth or another version of the truth, but seldom is it the whole truth. Their “yes” may means “yes” when swearing on a stack of Bibles in a courtroom, but it may not mean “yes” in other situations. Jesus is addressing this ungodly behavior in our passage.
