Melachim Bais 3:12 Meaning and Commentary

2 Kings 3:12

And Jehoshaphat said, the word of the Lord is with him
To give them an answer, which he concluded from his being a servant and disciple of Elijah, whom he succeeded in his office, and of whom he had, doubtless, heard; and from his following the camp, and being in it, which he easily imagined was not to fight, but to assist by his advice and counsel, and by his prophecies, as there might be occasion for them:

so the king of Israel and Jehoshaphat and the king of Edom went down to
him;
descended from their chariots, and went to the tent in the camp where he was; they did not send for him to come to them, but, in honour of him, went to him themselves.

Melachim Bais 3:12 In-Context

10 And Melech Yisroel said, Alas that Hashem hath called these three melachim together, to deliver them into the yad Moav!

11 But Yehoshaphat said, Is there not here a navi of Hashem, that we may inquire of Hashem through him? And one of the avadim of Melech Yisroel answered and said, Here is Elishah Ben Shaphat, which poured mayim on the hands of Eliyahu.

12 And Yehoshaphat said, The Devar Hashem is with him. So Melech Yisroel and Yehoshaphat and Melech Edom went down to him.

13 And Elishah said unto Melech Yisroel, What have I to do with thee? Get thee to the [Ba’al] nevi’im of Avicha, and to the nevi’im of Immecha. And Melech Yisroel said unto him, No; for Hashem hath called these three melachim, to deliver them into the yad Moav.

14 And Elishah said, As Hashem Tzva’os liveth, before whom I stand, surely, were it not that I regard the presence of Yehoshaphat Melech Yehudah, I would not look toward thee, nor see thee.
