'Fast' in the Bible

And Jael wife of Heber taketh the pin of the tent, and taketh the hammer in her hand, and goeth unto him gently, and striketh the pin into his temples, and it fasteneth in the earth -- and he hath been fast asleep, and is weary -- and he dieth.

And all the sons of Israel go up, even all the people, and come in to Beth-El, and weep, and sit there before Jehovah, and fast on that day till the evening, and cause to ascend burnt-offerings and peace-offerings before Jehovah.
