The King that was visited by the Wise Men was King Herod
The three wise men, or Magi, first encountered King Herod when they arrived in Jerusalem seeking the newborn King of the Jews. They sought Herod's guidance to find Jesus, as they had seen his star in the east. Herod, troubled by their inquiry, instructed them to find the child and report back to him, intending to locate Jesus for his own purposes.
Bethlehem
Matthew 2 tells about the wise men comming to see Jesus in Bethlehem. The wise men talk to King Herod and tell him they are looking for the saviour. Herod tries to trick the wise men into revealing where the saviour is but the wise men are warned in a dream and don't see Herod again. Herod realizes the wise men have tricked him and so he plans to kill all male children under two years old. Joseph is warned in a dream and him and Mary their son go to live in Egypt until Herod dies.
Because after the wise men visited Herod and asked about the new king, Herod order children 2 and under to be slaughtered all we know is that Jesus must have been under 2 years of age. Tradition tells us that there were 3 gifts but we are not sure of the number of wise men that made the journey and that Jesus was probably in the city and not the stable when they arrived.
Jesus was likely around two years old when the wise men visited him.
King Herod asked the wise men to tell him where he could find Jesus, because Herod wanted to kill Jesus.
Jesus was visited by the 3 wise men who brought him gifts of Myrrh, Frankincense and gold.
The wise men followed the star to Jerusalem and then asked Herod the Great where the "new born King" was to be born. Herod inquired of the chief priests and scribes and they told him, Bethlehem. Then the wise men followed the star to where Jesus was.
An angel of the Lord warned the wise men in a dream about King Herod's intention to kill Jesus. Following this divine warning, the wise men chose not to return to Herod and instead took a different route back to their country. This event is described in the Gospel of Matthew, specifically in Matthew 2:12.
We celebrate December 25th as the day when the wise men visited the baby Jesus.
Matthew 2:1-12 Though it doesn't specify the number of wise men who visited, nor the age of Jesus (it is assumed he was between the ages of newborn to 2 years of age, depending on with whom you speak.) It is assumed from the three gifts, gold, frankinscence and myhrr, that there were three Magi (wise men; magicians?), in later traditions called kings, and even given names. **It should be noted that they first approached Herod, who then ordered the deaths of all infants under the age of three.
