Final answer:
Jesus was approximately 2 years old when the wise men visited him, based on the account of King Herod's order to kill all male children under the age of two.
Step-by-step explanation:
Jesus was approximately 2 years old when the wise men, also known as the Magi, brought him gifts. This approximation is derived from the Biblical account in which King Herod, after learning of Jesus's birth and fearing the rise of a new 'King of the Jews,' orders the massacre of all male children in Bethlehem who were two years old and under, according to the time he ascertained from the Magi (Matthew 2:16). Therefore, it suggests that Jesus could have been up to 2 years old during the visit of the wise men. However, the exact age cannot be determined with certainty from the scriptures.
