Did Elisha receive Elijah's mantle before or after Elijah is taken up into heaven?

So he ... found Elisha ... and Elijah passed by him, and cast his mantle upon him. 1 Kings 19:19

Elijah went up by a whirlwind into heaven. He [Elisha] took up also the mantle of Elijah that fell from him. 2 Kings 2:11-13
