The visit of the wise men.
v.1 Jesus was born in Bethlehem in Judea, during the reign of King Herod. After his birth wise men (Magi, NIV) from the east came looking for him. (This occurred perhaps 1 or 2 years after the birth).
v.2 In Jerusalem, the wise men ask where the newborn king is so they could worship him. They had seen his star when it rose. This seems to imply that the men were astrologers and were familiar with OT prophecy.
v.3-6 Herod was troubled about the wise men and called together the chief priests and scribes and asked where the Christ was to be born. They told him the Christ was to be born in Bethlehem in Judea (Mi 5:2).
v.7-8 Herod met with the wise men secretly and asked when the star had first appeared to them. He then told them to go to Bethlehem and look there for the child and bring him word so that he might worship him too.
v.9-10 The wise men journeyed to Bethlehem and the star appeared to them again and came to rest over where the child was. When they saw the star they rejoiced greatly.
v.11 They went into the house and saw the child and his mother, Mary. They worshiped baby Jesus and offered him gifts of gold, frankincense and myrrh. These are appropriate gifts for a king.
v.12 The wise men were warned in a dream not to return to Herod so they went home by another route.
