Deuteronomy 9:18-19

Webster(i) 18 And I fell down before the LORD, as at the first, forty days and forty nights: I neither ate bread, nor drank water, because of all your sins which ye sinned, in doing wickedly in the sight of the LORD, to provoke him to anger. 19 (For I was afraid of the anger and hot displeasure with which the LORD was wroth against you to destroy you.) But the LORD hearkened to me at that time also.
