Septuagint

And I was greatly terrified because of the wrath and anger,because the Lord was provoked with you to utterly destroy you 

New Testament

and so fearful was the appearance, that Moses said, I exceedingly fear and quake
 

Masoretic Text

For I was afraid of the anger and hot displeasure, wherewith Jehovah was wroth against you to destroy you

Comments:  The NT, LXX and MT agree.  The New Testament author has added the thought of trembling or  “quaking.”
