This shelter in the wilderness will save Israel from the Dragon as it pursues after the Woman in Revelation 12; just as God saved Israel from the Pharaoh of Egypt as he pursued them leaving Egypt.

..............................................God saved them as it were on "eagles wings" and Pharaoh perished as a victim of God's judgment.

.......................As God's people on earth will be the 'Church in the Wilderness' in the Great Tribulation just as Israel was called 'the Church in the Wilderness' when she fled from Pharaoh.
....................................Acts 7:38
"This is he, that was in the church in the wilderness with the angel which spake to him in the mount Sina, and with our fathers: who received the lively oracles to give unto us:. . ."
