How does that show up in The Book of Exodus? Where is Jesus in Exodus?
The Father has not been seen but Jesus makes him known - so The Seen God is the Son. Seems to me that we see Jesus on stage in Exodus, and we see him foreshadowed in the events of the Exodus. He is The Exodus and seen in many of its components... and then there's The Tabernacle that sets almost the entire grammar for understanding the cross.
In Exodus Jesus is
1v17 The true midwife, protecting the people of God...
2v10 The true Moses drawn up out of the water...
2v23 The true answer to the salvation cry of God's image bearers...
3v2 The Angel of the LORD who appeared to Moses
3v6 The God of Abraham, Isaac and Jacob
3v15 The I AM
3v18 He who calls his people out of slavery to meet with him
4v22 The true son, foreshadowed by Israel God's Son
4v25 The bridegroom of blood
6v9 He who will rescue a people whose spirits are broken by their slavery
6v25 The True and Greater Phinehas...
7v1 Pictured by Moses and Aaron, God and prophet to Pharaoh
7v17 He who contends with tyrannical Pharaoh, decreating Egypt
10v23 He who puts his enemies in darkness, and shine light on his people
10v27 He who hardens Pharaoh, as he also softens us
12v5 The true passover lamb, without blemish, whose blood was shed for his people
12v12 He who passed through Egypt in judgement
14v14 The one who fights for his people
14v24 He who was in the fire and cloud
14v30 He who saved his people
15v1 The triumphant one
15v13 The loving redeemer
16v4 The true bread of heaven
17v6 The struck rock, from whom life flows
17v15 Our Banner, whose name is love...
18v21 The truly trustworthy man, model for every other leader
19v11 The LORD who says the LORD (his Father) will come to the mountain on the third day
20v5 He whose name is jealous
22v22 He who will not have widows, orphans and foreigners mistreated
24v8 The blood of our covenant
24v11 He who was seen by and ate dinner with representatives of the people
25v9 He who would offer himself not in the model tabernacle but in the heavenly one. Much as Sinai is about the giving of law it's the Tabernacale that dominates Exodus - this is a story about God dwelling with his people and Jesus is on stage at the heart of it all...
Not to mention, that Jesus is the one who came and Tabernacled among us...
28v29 The true priest who has our names on his breastplate and carries us in on his heart
33v11 He who met with Moses face to face, as with a friend
33v16 He whose presence makes his people distinctive
33v19 He whose glory is his goodness
34v14 He whose name is Jealous
34v19 He who made Moses face shine
"Exodus 38:8 Jesus kindly uses our gifts to make his church beautiful like Bezalel used those women's mirrors to make the tent beautiful" @John_Hindley
40v34 He who was always with his people in the wilderness.
The book of Exodus tells the gospel story in its drama, foreshadowing what Jesus would do in his incarnation, when he became an Israelite - a member of the nation he rescued, and set them free to be free forever through his life, death and resurrection, which makes his dwelling with us by his Spirit possible.
