'Excused' in the Bible

"How terrible it will be for you, blind guides! You say, "Whoever swears an oath by the sanctuary is excused, but whoever swears an oath by the gold of the sanctuary must keep his oath.'

Again you say, "Whoever swears an oath by the altar is excused, but whoever swears by the gift that is on it must keep his oath.'

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

And another said, I have bought five yoke of oxen, and I go to prove them: I pray thee have me excused.

If, however, I have done wrong and have committed any offence for which I deserve to die, I do not ask to be excused that penalty. But if there is no truth in what these men allege against me, no one has the right to give me up to them as a favour. I appeal to Caesar."
