'Oath' in the Bible

But I say to you, do not make an oath at all, either by heaven, for it is the throne of God;

so much that he promised with an oath to give her whatever she asked.

“Woe to you, blind guides, who say, ‘Whoever swears [an oath] by the sanctuary of the temple, that is nothing (non-binding); but whoever swears [an oath] by the gold of the temple is obligated [as a debtor to fulfill his vow and keep his promise].’

And [you scribes and Pharisees say], ‘Whoever swears [an oath] by the altar, that is nothing (non-binding), but whoever swears [an oath] by the offering on it, he is obligated [as a debtor to fulfill his vow and keep his promise].’

And again he denied it with an oath, “I do not know the man.”
