Something I took note of this time reading Exodus, which I don't remember much from previous readings, is how God spoke to Moses face to face (33:11 - The Lord would speak to Moses face to face, as a man speaks to a friend.) as He had not done with any other man. Also earlier in 6:2-3 God says, 'I am the Lord. I appeared to Abraham, Isaac and Jacob as God Almighty, but by my name the Lord I did not make myself known to them.' I found that fascinating, God revealing a new aspect of Himself to His people!
What an amazing God we have!
