Final answer:
According to Luke 2:7, Jesus was put into a manger because there was no room for his parents in the inn, highlighting the humble circumstances of his birth.
Step-by-step explanation:
According to Luke 2:7, Jesus was put into a manger because there was no room for Mary and Joseph in the inn. At the time of Jesus' birth, the town of Bethlehem was crowded due to a census ordered by the Roman government. Joseph and Mary, unable to find lodging in the inn, had to seek shelter where they could. This led to Mary giving birth to Jesus in a setting where animals were kept and placing him in a manger, which is a feeding trough for animals. This event is a significant part of the Nativity story that underscores the humble circumstances of Jesus' birth.
