Then it happened, as they continued on and talked, that suddenly a chariot of fire appeared with horses of fire, and separated the two of them; and Elijah went up by a whirlwind into heaven. 2 Kings 2:11

Before his translation into heaven, Elijah and Elisha walked around from place to place, all of which have great spiritual significance.
They went to Bethel, where God appeared to Jacob (Israel) twice. It is the place Jacob dreamed of a stairway to heaven with angels ascending and descending. Jacob said that surely God was in this place. But now the city is host to a golden calf idol, set up by the King Jeroboam of Israel.
While there fifty prophets told Elisha the Lord would take Elijah away that day.
They traveled to Jericho, where the God gave the Israelites their first great victory upon entering the Promised Land by obediently walking around the city.
However, more recently, the rebuilding of the city took a heavy toll on the builder.
At Jericho, the sons of the prophets reiterated the message of those in Bethel.
They came to the Jordan River, where Elijah took his mantle and parted the waters, just as the priest had done when Israel entered the land.
On the other side of this river is where Moses died centuries before, having seen the Promised Land but not allowed to enter it.
In this land of Moab, the Israelites sinned against God with the Moabites and their gods.

Each place they visited was a place of great sorrow from sin and a great visitation of God.

The Bible does not indicate this, but I wonder if perhaps they walked to the valley where God buried Moses (Deut 34) and this was where God took Elijah.
How appropriate for the two to come together.
It is the coming together of the Law (Moses) and the Prophets (Elijah) in the same place.
It is these two seen with Jesus at His transfiguration (Matt 17:1-4).
I believe these two become the witnesses of Revelation 11.

I am reminded of this scripture in Romans that speaks of the Law and the Prophets. I think it’s appropriate here.
Rom 3:21-26
But now the righteousness of God apart from the law is revealed, being witnessed by the Law and the Prophets, even the righteousness of God, through faith in Jesus Christ, to all and on all who believe. For there is no difference; for all have sinned and fall short of the glory of God, being justified freely by His grace through the redemption that is in Christ Jesus, whom God set forth as a propitiation by His blood, through faith, to demonstrate His righteousness, because in His forbearance God had passed over the sins that were previously committed, to demonstrate at the present time His righteousness, that He might be just and the justifier of the one who has faith in Jesus.
