Melachim Alef 22:15

15 So he came to HaMelech. And HaMelech said unto him, Mikhay’hu, shall we go against Ramot-Gil‘ad to battle, or shall we refrain? And he answered him, Go, and succeed: for Hashem shall deliver it into the yad HaMelech.

Melachim Alef 22:15 Meaning and Commentary

1 Kings 22:15

So he came to the king
Being introduced by the officer:

and the king said unto him, Micaiah, shall we go up against
Ramothgilead to battle, or shall we forbear?
the same question in the same words that was put to the other prophets, ( 1 Kings 22:6 ) , only there he uses the singular number, here the plural, including Jehoshaphat with him:

and he answered him, go, and prosper: for the Lord shall deliver [it]
into the hand of the king;
he answered not in the name of the Lord, saying, "thus saith the Lord", nor did he speak his own sense and in his own words, nor seriously, but by way of derision; he took up the words of the prophets, and bantered them; it is as if he should say, the prophets bid you go, and tell you that you shall "prosper", and that the city will be delivered into the king's hand; do as they direct you, and see what the issue will be, no doubt it will be good, since they are all agreed; but he delivered the above words with such gestures, and such a tone, and with a contemptuous smile in his countenance, which showed that he spoke not seriously, but sarcastically; and this the king plainly discovered, as appears by what follows.

Melachim Alef 22:15 In-Context

13 And the malach that was gone to summon Mikhay’hu spoke unto him, saying, Hinei now, the words of the nevi’im declare tov unto HaMelech with one mouth: let thy word be like the word of one of them, speak that which is tov.

14 And Mikhay’hu said, As Hashem liveth, what Hashem saith unto me, that will I speak.

15 So he came to HaMelech. And HaMelech said unto him, Mikhay’hu, shall we go against Ramot-Gil‘ad to battle, or shall we refrain? And he answered him, Go, and succeed: for Hashem shall deliver it into the yad HaMelech.

16 And HaMelech said unto him, How many times shall I adjure thee [i.e., make thee swear] that thou tell me nothing but that which is true in the Shem of Hashem?

17 And he said, I saw kol Yisroel scattered upon the hills, as Tzon that have not a Ro’eh: and Hashem said, These have no adonim: let them return every man to his bais in shalom.
