'Rude' in the Bible
A senseless man [in his crude and uncultivated state] knows nothing,Nor does a [self-righteous] fool understand this:
and she is never rude; she never thinks just of herself or ever gets annoyed. She never is resentful;
But though I be rude in speech, yet not in knowledge; but we have been throughly made manifest among you in all things.
For since the Law has only a shadow [just a pale representation] of the good things to come—not the very image of those things—it can never, by offering the same sacrifices continually year after year, make perfect those who approach [its altars].
