It is not so clearly proved as to leave the point unquestionable, whether Moses means a second continuance and abstinence of forty days and nights in the mount as before. The particular manner of wording the expression, that he fell down before the LORD, in the same way as he did when he was forty days and forty nights in the mount with the LORD; this seems as if he meant to say, that his intercession was similar in manner not in time. Moreover, if Moses really was a second time forty days and forty nights in the mount, there is no mention made of his employment the second time like the first. See Exodus 24:18. And as Moses was eminently a type of the ever-blessed JESUS, we see a manifest propriety in the first forty days; but, considered as a type of JESUS in his fasting, the second would lessen its effect on this account. I do not, however, venture to speak decidedly upon the subject; but leave the Reader to his own judgment under the SPIRIT's teaching. See Matthew 4:2.
