פירוש על מלכים ב 2:14

Where is Adonoy, the God of Eliyahu? That I was promised that a double portion of his spirit would rest upon me.⁹Alternatively, where is God who does not show me His sign as He showed Eliyahu is the splitting of the water?”—Ralbag

Then he also struck the water. He too. In the Chapters of Rabbi Eliezer, son of Rabbi Yose Haglili, [it states that] Elisha’s splitting [the Yardein] was twice as great as Eliyahu’s, for in the beginning there was the merit of them both, and now there was his merit alone.¹⁰See Rashi 3:1 below. Thus, Elisha’s request for twice Eliyahu’s spirit had been fulfilled.
