Matthew Poole and continuators on 2 Kings 2:1

AND it came to pass, when the LORD would take up Elijah into heaven by a whirlwind, that Elijah went with Elisha from Gilgal.

a This he desires, Either, 1. That he being left alone, might better prepare himself for his great Change. Or, 2. Out of his Humility and Modesty: he desired no Witnesses of his Glorious Removal▪ and no Fame and Glory from it. Or, 3. Out of Indulgence to Elisha, that he might not be overwhelmed with Grief at so sad a sight. Or, 4. That he might trie his Love, and whet his desire to accompany him; it being highly convenient for God's honour, and the Churches good, (which Elijah sought above all things) that there should be Witnesses of so glorious a Translation.
