'Sworn' in the Bible

Or when a person swears, speaking thoughtlessly with [his] lips, to do evil or to do good {with regard to} anything that {the person} in a sworn oath speaks thoughtlessly, but {he is unaware of it}, he will be guilty {in any of} these.

or {regarding} anything about which he has sworn {falsely}, then he shall repay it {according to} its value and shall add one-fifth of its value to it--he must give it {to whom it belongs} on the day of his guilt offering.
