Paul says to let 2 or 3 prophets speak in turn, each discerned in turn, and if necessary, paused by other prophets. The math points at the collusion of Ahab's 400 false prophets as an example of what Paul wants to avoid.

1 Corinthians 14:26-33

26Therefore I say to you, my brothers, when you gather together whoever among you 1|5 has a psalm to sing, 2|5 has a teaching, 3|5 has a revelation, 4|5 has the gift of tongues, 5|5 or has the gift of interpretation, let everything be done for edification. 27If any man should speak in an unknown tongue, let 2 or at most 3 speak, and speak one by one, and let one interpret. 28But, if there is no one to interpret, let him who speaks in an unknown tongue keep silent in the assembly, and let him speak to himself and to god. 1 Corinthians 14:26-2829Let the prophets speak 2 or 3 in turn, and let the others discern what is said. 30If anything is revealed to another who is seated, let the 1st speaker hold his peace. 31For you may all prophesy one by one, so that everyone may learn and everyone be comforted. 32For the spirits of the prophets are subject to the prophets. 33For god is not a god of confusion but of peace. 1 Corinthians 14:29-33As in all assemblies of the holy 1 Corinthians 14:33-35 (1 Corinthians 14:26-33 BRB)


2+3+2+3 = 10 = First Kings

1 Kings

Paul's rules on prophesying in an assembly are intended to protect from collusion. The story that best exemplifies this problem in all of scripture is the story in First Kings where Ahab decides to go to battle and after the fact has a horde of false prophets agree that he should do this and that he will in fact be victorious. The lone dissenting voice of truth that follows the false prophecy is marginalized and the king dies for not listening to the true word.

FE 13 years passed without war between Adam and Israel. 2It came to pass in the 3rd year that Jehoshaphat king of Judah came down to Ahab king of Israel. 3The king of Israel said to his servants, You know that Ramoth Gilead belongs to us. How long will we keep still and not take it out of the hand of the king of Adam? 1 Kings 22:1-34He said to Jehoshaphat, Will you go with me to battle to Ramoth Gilead? 1 Kings 22:4Jehoshaphat said, I will go as you go and my people as your people and my horses as your horses. 5Jehoshaphat said to the king of Israel, Enquire I ask for the word of the Master this day. 1 Kings 22:4-56The king of Israel gathered the prophets together, about 400 men, and said to them, Should I go to Ramoth Gilead to battle or should I refrain? 1 Kings 22:6aThey said, Go up for master will deliver them into your hands king. 1 Kings 22:6b7Jehoshaphat said, Is there not here a prophet of the Master that we might ask him? A Hebrews 12:19 1 Kings 22:78The king of Israel said to Jehoshaphat, There is yet 1 man by whom we may ask the Master, but I hate him for he does not prophesy good concerning me but evil. A Matthew 5:13 A 2 Corinthians 6:6 FE His name is Micah son of Imlah. 1 Kings 22:8aJehoshaphat said, Do not let the king say so. 1 Kings 22:8b9The king of Israel called 1 eunuch and said to him, Quickly, Micah FE son of Imlah. 1 Kings 22:910The king of Israel and Jehoshaphat king of Judah were each seated on his throne and wearing robes of different colors at the entrance of the gate of Samaria and all the prophets were prophesying before them. 11Zedekiah, the son of a Canaanitess, made for himself horns of iron and said, The Master says, With these you will pierce the Adamites until you have destroyed them. 1 Kings 22:10-1112All the prophets prophesied so, and they were saying, Go up to Ramoth Gilead and conquer and the Master will deliver them into your hands king. 1 Kings 22:1213The messenger who went to call Micah spoke to him saying, The words of the lying prophets from 1 mouth say good concerning the king. Let your word be like the word of 1 of them and you also speak good. 1 Kings 22:1314Micah said, As the Master lives, whatever the Master says to me that I will speak. 1 Kings 22:1415He came to the king and the king said to him, Micah, should we go to Ramoth Gilead to battle or should we refrain? 1 Kings 22:15aHe said to him, Go up and conquer and the Master will deliver them into your hands king. 1 Kings 22:15b16The king said to him, How many times have I adjured you that you tell me nothing except what is true in the name of the Master? 1 Kings 22:1617Micah said, I saw Israel scattered on the mountains like sheep that have no shepherd. The Master said, These have no master. Let each man return to his own house in peace. 1 Kings 22:1718The king of Israel said to Jehoshaphat, Did I not tell you that he would not prophesy good concerning me but evil? 1 Kings 22:1819Micah said, Hear therefore the word of the Master. I saw the Master sitting on his throne and all the host of the skies standing by him on his right hand and on his left. 20The Master said, Who will persuade Ahab that he may go up and fall at Ramoth Gilead. 1 Kings 22:19-20One said in this manner and another said in that manner. 21A spirit came forth and stood before the Master and said, I will persuade him. 1 Kings 22:20-2122The Master said to him, By what means? 1 Kings 22:22aHe said, I will go forth and will be a lying spirit in the mouth of all his prophets. 1 Kings 22:22bHe said to him, You will persuade him and also prevail. Go forth and do so. 1 Kings 22:22c23Now the Master has put a lying spirit in the mouth of all these prophets and the Master has spoken evil concerning you. A Proverbs 12:5 1 Kings 22:2324Zedekiah, the son of the Canaanitess, went near and struck Micah on his cheek and said to him, Which way has the spirit of the Master departed from me and spoken to you? 1 Kings 22:2425Micah said to him, You will see in that day when you will go into an inner chamber to hide yourself. 1 Kings 22:2526The king of Israel said, Take Micah and deliver him to Amon the governor of the city and to Joash the son of the king 27and say, Thus says the king, Put this fellow in the house of prisoners and feed him with bread to preserve life and with water to preserve life until I come in peace. 1 Kings 22:26-2728Micah said, If you return in peace then the Master has not spoken by me. He said, Hear all you people. 1 Kings 22:2829The king of Israel and Jehoshaphat king of Judah went up to Ramoth Gilead. 30The king of Israel said to Jehoshaphat, I will disguise myself and enter into the battle and you put on your robes. The king of Israel disguised himself and went into the battle. 1 Kings 22:29-3031The king of Adam commanded the 32 captains of his chariots saying, Do not fight with small nor great, but with the king of Israel only. 32When the captains of the chariots saw Jehoshaphat they thought he was the king of Israel and they turned aside to fight with him. Jehoshaphat cried out 33and when the captains of the chariots saw that he was not the king of Israel they turned back from pursuing him. 1 Kings 22:31-33341 man drew his bow toward him at a venture and struck the king of Israel between the joints of the breastplate and he said to his charioteer, Turn your hand and take me from the camp because the pangs of death have come on me. 35The battle grew fiercer that day and the king was standing in the chariot facing Adam and died that evening and the blood ran out of his wound into the hollow of his chariot. I Isaiah 10:4 1 Kings 22:34-3536A herald called in the camp when the sun had set and said, Go every man to his city and every man to his land. 1 Kings 22:36 (1 Kings 22:1-36 BRB)

Note especially the scene in the throne room in the skies in verses 19-22, because it demonstrates the proper flow for prophesying in an assembly. Yahvah is on the throne. There are a host of others. One comes forward with a word, then another, then another, each in turn. Eventually a true word comes and is carried out.
