Here are a few verses from the New World Translation found at JW.org.
Exodus 6:2-3
2 Then God said to Moses: “I am Jehovah.
3 And I used to appear to Abraham, Isaac, and Jacob as God Almighty, but with regard to my name Jehovah I did not make myself known to them.
Here Jehovah is said to appear to Abraham, Isaac, an Jacob as God Almighty.
Genesis 32:30
30 So Jacob named the place Pe·niʹel,* for he said, “I have seen God face-to-face, yet my life* was preserved.”
Here Jacob sees God face to face.
Exodus 33:11
11 Jehovah spoke to Moses face-to-face, just as one man would speak to another man. When he returned to the camp, Joshua the son of Nun, his minister and attendant, would not depart from the tent.
Here Jehovah spoke with Moses face to face as one man would speak to another man.
Finally we read in John 1 the following:
John 1:18
18 No man has seen God at any time; the only-begotten god who is at the Father’s side is the one who has explained Him.
Here we learn that, speaking of God the Father, no man has seen Him. If no man has seen God the Father up until the time John wrote his gospel, then who was Jehovah who appeared to Abraham, Isaac, and Jacob? Who was God that Jacob saw face to face? Who was Jehovah that spoke to Moses face to face? If, according to John 1:18, no man has see God the Father at any time, who was it that was seen by all the prophets mentioned above? Was it not Jesus who proclaimed that He was I AM (John 8:58)? The God who saved Israel from the land of Egypt, is He not the Savior?
Isaiah 43:3
3 For I am Jehovah your God, The Holy One of Israel, your Savior. I have given Egypt as a ransom for you, E·thi·oʹpi·a and Seʹba in exchange for you.
Hosea 13:4
4 But I am Jehovah your God from* the land of Egypt; You knew no God except me, And besides me there is no savior.
Exodus 6:2-3
2 Then God said to Moses: “I am Jehovah.
3 And I used to appear to Abraham, Isaac, and Jacob as God Almighty, but with regard to my name Jehovah I did not make myself known to them.
