'Rashly' in the Bible

Or if any one swear rashly with his lips to do evil, or to do good, whatsoever it be that a man shall utter rashly with an oath, and it be hid from him; when he knoweth of it, then he shall be guilty in one of these things .

There is that speaketh rashly like the piercings of a sword; But the tongue of the wise is health.

It is a snare to a man rashly to say, It is holy, And after vows to make inquiry.
