'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.'

Every single one of them began asking to be excused. The first told him, "I bought a field, and I need to go out and inspect it. Please excuse me.'
