John Gill Bible Commentary

You have been rebellious against the Lord from the day that I knew you. Either from the time he first had and took knowledge of them and visited them, before his departure from Egypt to the land of Midian; (see Exo 2:11 compared with Act 7:25); or from the time that he was sent to them to deliver them out of Egypt; see Exo 5:20 and especially from the time he brought them into the wilderness. and especially from the time he brought them into the wilderness. Deuteronomy 9:25 deu 9:25 deu 9:25 deu 9:25Thus I fell down before the Lord forty days and forty nights, as I fell down at the first,.... Which Jarchi says are the selfsame said above, Deu 9:18, but doubled or repeated, because of the order of his prayer. The words "at the first" are not in the text; and, as before observed, we do not read that Moses fell down at the first forty days he was in the mount, unless it can be thought he did, Exo 32:11, wherefore this falling down seems to be as he fell down at the second forty days; and so this was a third forty days, according to the Jewish writers, and of which opinion were Dr. Lightfoot and others; See Gill on Exo 34:28, because the Lord had said he would destroy you; threatened them with destruction, and seemed as if it was his intention to destroy them; nay, even after Moses's first prayer, though he bid him go and lead the people on, yet he declared that he would visit their sin upon them, Exo 32:34.
