וַיִּקַּח֩ אֶת־אַדֶּ֨רֶת אֵלִיָּ֜הוּ אֲשֶׁר־נָפְלָ֤ה מֵֽעָלָיו֙ וַיַּכֶּ֣ה אֶת־הַמַּ֔יִם וַיֹּאמַ֕ר אַיֵּ֕ה יְהוָ֖ה אֱלֹהֵ֣י אֵלִיָּ֑הוּ אַף־ה֣וּא ׀ וַיַּכֶּ֣ה אֶת־הַמַּ֗יִם וַיֵּֽחָצוּ֙ הֵ֣נָּה וָהֵ֔נָּה וַֽיַּעֲבֹ֖ר אֱלִישָֽׁע׃
And he took the mantle of Elijah that fell from him, and smote the waters, and said: ‘Where is the LORD, the God of Elijah?’ and when he also had smitten the waters, they were divided hither and thither; and Elisha went over.
Rashi on II Kings
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
Rashi on II Kings
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.
