John Gill Commentary 2 Kings 2:1

"And it came to pass, when Jehovah would take up Elijah by a whirlwind into heaven, that Elijah went with Elisha from Gilgal." — 2 Kings 2:1 (ASV)

And it came to pass, when the Lord would take up Elijah
into heaven by a whirlwind
Thereby lifting him up from the earth, and which, as it was the purpose and will of God, Elijah had notice of, as appears by his motions to different places, under a divine direction:

that Elijah went with Elisha from Gilgal ,
where it seems they met, a place where the Israelites first pitched when they came over Jordan, and where the tabernacle was for some time, and was famous for religious services, see (Joshua 4:19) (5:9) .
