'Excuse' in the Bible

If I had not come and spoken to them, they would not have sin, but now they have no excuse for their sin.

For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse.

Therefore you have no excuse, everyone of you who passes judgment, for in that which you judge another, you condemn yourself; for you who judge practice the same things.
