The Bible doesn’t say how many Wise Men there were and it doesn’t mention a manger!
Matthew 2: 9-12 Complete Jewish Bible
9 After they (Magi-Wise Men) had listened to the king, they went away; and the star which they had seen in the east went in front of them until it came and stopped over the place where the child was. 10 When they saw the star, they were overjoyed. 11 Upon entering the house, they saw the child with his mother, Miryam; and they prostrated themselves and worshipped him. Then they opened their bags and presented him gifts of gold, frankincense and myrrh. 12 But they had been warned in a dream not to return to Herod, so they took another route back to their own country.
