Not to eat
I shall endeavor to show, first, what is the nature of fasting, and what the several sorts and degrees of it. As to the nature of it, all the inspired writers, both in the Old Testament and the New, take the word to fast in one single sense, for not to eat, to abstain from food. This is so clear that it would be labor lost to quote the words of David, Nehemiah, Isaiah, and the prophets who followed, or of our Lord and his apostles, all agreeing in this, that to fast is not to eat for a time prescribed.

I. 1. I shall endeavour to shew, first, what is the nature of fasting, and what the several sorts and degrees thereof. As to the nature of it, all the inspired writers, both in the Old Testament and the New, take the word, to fast, in one single sense, for not to eat, to abstain from food. This is so clear, that it would be labour lost to quote the words of David, Nehemiah, Isaiah, and the prophets which followed, or of our Lord and his apostles; all agreeing in this, that, to fast, is not to eat for a time prescribed.
