John Gill Commentary 2 Kings 2:15

"And when the sons of the prophets that were at Jericho over against him saw him, they said, The spirit of Elijah doth rest on Elisha. And they came to meet him, and bowed themselves to the ground before him." — 2 Kings 2:15 (ASV)

And when the sons of the prophets, which were to view at
Jericho, saw him
Who went out from thence towards Jordan, to have a sight if they could of the assumption of Elijah; these, when they saw Elisha come over Jordan, the waters being parted by him.

they said, the spirit of Elijah does rest on Elisha ;
or he has the same power and spirit to work miracles as he had, which they discerned by his dividing the waters of Jordan with his mantle.

and they came to meet him, and bowed themselves to the ground before
him ;
in reverence of him as their master, in the room of Elijah.
