“Letter” can mean the written form of a command or the outward form of obedience. Paul contrasts the oldness of the letter, associated with the written Mosaic law, with the newness of the Spirit.
Definition
In Acts 18:14, “lewdness” means wickedness, villainy, or unlawful conduct, not specifically sexual immorality in the modern restricted sense.
Biblical Usage
The term appears when Gallio refuses to judge a matter involving alleged wrongdoing that did not constitute a serious crime or legal offense.
Historical Background
The English word originally carried the sense of being ignorant or unlearned and then came to mean low or vicious conduct.

In Rom. 2:27, 29 means the outward form. The “oldness of the letter” (7:6) is a phrase which denotes the old way of literal outward obedience to the law as a system of mere external rules of conduct. In 2 Cor. 3:6, “the letter” means the Mosaic law as a written law. (See WRITING.)
