'Excuse' in the Bible

And they all with one consent began to make excuse. The first said unto him, I have bought a field, and I must needs go out and see it; I pray thee have me excused.

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

For the invisible things of him since the creation of the world are clearly seen, being perceived through the things that are made, even his everlasting power and divinity; that they may be without excuse:

Wherefore thou art without excuse, O man, whosoever thou art that judgest: for wherein thou judges another, thou condemnest thyself; for thou that judgest dost practise the same things.
