Translation
And he said, “Therefore, hear the word of YHVH (read Adonai), I saw YHVH (read Adonai) sitting on His throne and all the army of heavens standing over against [Him] on the right and on the left.
Paraphrase
Micaiah continued, “Based on what I said a moment ago, you need to listen and hear the verdict of THE ETERNAL AND PERSONAL GOD concerning you. The vision I saw had no time markers, so I don’t know when this part happened and it doesn’t matter. The main point is that I saw THE ETERNAL AND PERSONAL GOD in His position of authority, ready to issue a command, with all His heavenly army [of angels] on their feet ready to obey any command and facing Him anticipating a command; there were so many that they had to position themselves in an arc from the far right to the far left of Him.
THIS VISION GETS A BIT STRANGE
The absence of time in his vision will prove to be important very soon.
Notice that all of those in the vast army of God are waiting for Him to give them a command and they will do it. They do not give Him advice, or counsel. They do not make suggestions. They simply wait, and then obey.
However, at this point in his retelling of the vision, the prophet Micaiah begins to present things in a way that King Ahab will understand. Ahab had been so highly influenced by paganism from his wife, Jezebel, and others around him that he now thought like they did. Whether God instructed the prophet Micaiah to say it this way, or whether the prophet took the main point God wanted him to make and wrapped it in a package that Ahab would easily grasp, we do not know for sure. I think it was by God’s direct instruction, for that is how all the good prophets functioned; they did not change the message.
