Fasting, by definition, is abstaining from food or drink for a period of time. The term “fast” in the Bible comes from the Hebrew word “tsum” literally meaning to “cover the mouth”. [SOURCE: http://biblehub.com/hebrew/6684.htm] In the Greek language, it’s “néstis”. It combines né- (meaning not) and esthió (meaning to eat). [SOURCE: http://biblehub.com/greek/3523.htm] This is the kind of fasting we will talk about in this study. We’re not fasting social media or television. We’re fasting in the true Biblical sense and that is to not eat.
