John Gill Commentary 2 Kings 2:7

"And fifty men of the sons of the prophets went, and stood over against them afar off: and they two stood by the Jordan." — 2 Kings 2:7 (ASV)

And fifty men of the sons of the prophets went, and stood to
view afar off
To have a view, if they could, of the assumption of Elijah to heaven, and be witnesses of it:

and they two stood by Jordan ;
on the banks of it, even Elijah and Elisha.
