2 Kings 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.

14 And Elisha said to him, The Lord of hosts liveth, in whose sight I stand, if I were not ashamed of the cheer of Jehoshaphat, king of Judah, truly I had not perceived, neither I had beheld thee.
