Christians know it was Moses who lead the Children of Israel out of Egypt, yet they still do not know a very important detail of the Exodus. According to the Bible, God sent an Angel to accompany Moses. Concerning this Angel, God said to Moses: "for my name is in him".

Exodus 23:
20 Behold, I send an Angel before thee, to keep thee in the way, and to bring thee into the place which I have prepared.
21 Beware of him, and obey his voice, provoke him not; for he will not pardon your transgressions: for my name is in him.
22 But if thou shalt indeed obey his voice, and do all that I speak; then I will be an enemy unto thine enemies, and an adversary unto thine adversaries.

While the Children of Israel were on their way to the promised Land, Messengers were sent to the King of Edom asking permission to pass through their Country and Moses then explained it was an Angel that brought them forth out of Egypt:

Numbers 20:
15 How our fathers went down into Egypt, and we have dwelt in Egypt a long time; and the Egyptians vexed us, and our fathers:
16 And when we cried unto the Lord, he heard our voice, and sent an angel, and hath brought us forth out of Egypt: and, behold, we are in Kadesh, a city in the uttermost of thy border:

All Christians should read in Context the following passages that narrate the encounter of Moses with the Lord. Please note during the divine Encounter in Exodus 33 and as well in Exodus 34, "the Lord" proclaimed the name of "the Lord":

Exodus 34:
5 And the Lord descended in the cloud, and stood with him there, and proclaimed the name of the Lord.
6 And the Lord passed by before him, and proclaimed, The Lord, The Lord God, merciful and gracious, longsuffering, and abundant in goodness and truth,
7 Keeping mercy for thousands, forgiving iniquity and transgression and sin, and that will by no means clear the guilty; visiting the iniquity of the fathers upon the children, and upon the children's children, unto the third and to the fourth generation.

Exodus 33:
17 ... for thou hast found grace in my sight, and I know thee by name.
18 And he said, I beseech thee, shew me thy glory.
19 And he said, I will make all my goodness pass before thee, and I will proclaim the name of the Lord before thee; and will be gracious to whom I will be gracious, and will shew mercy on whom I will shew mercy.
20 And he said, Thou canst not see my face: for there shall no man see me, and live.

When we go to the New Testament, the Apostle Paul gave to the Church this very important Revelation about the Exodus of the Children of Israel from Egypt:

1 Corinthians 10:
1 Moreover, brethren, I would not that ye should be ignorant, how that all our fathers were under the cloud, and all passed through the sea;
2 And were all baptized unto Moses in the cloud and in the sea;
3 And did all eat the same spiritual meat;
4 And did all drink the same spiritual drink: for they drank of that spiritual Rock that followed them: and that Rock was Christ.

Also in the Gospel of John we find extremely important details that are still not understood by most Christians. In John Chapter 17, Jesus ask God, his Father, to be glorified with the Glory he had before the World was:

John 17:
2 As thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him.
3 And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.
4 I have glorified thee on the earth: I have finished the work which thou gavest me to do.
5 And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was.

Also in the Gospel of John, it is revealed that in the beginning was the Light, and it dwelt among its own people and was rejected. This indicates a previous interaction, of Christ with the Children of Israel.

Isaiah 63:
8 For he said, Surely they are my people, children that will not lie: so he was their Saviour.
9 In all their affliction he was afflicted, and the angel of his presence saved them: in his love and in his pity he redeemed them; and he bare them, and carried them all the days of old.

John 1:
1 In the beginning was the Word, and the Word was with God, and the Word was God.
2 The same was in the beginning with God.
3 All things were made by him; and without him was not any thing made that was made.
4 In him was life; and the life was the light of men.

John 1:
10 He was in the world, and the world was made by him, and the world knew him not.
11 He came unto his own, and his own received him not.
12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:
13 Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
