It happened on the next day that the people rose early, and built there an altar, and offered burnt offerings and peace-offerings.
Then the Israelites sought the Lord more seriously (Judges 21:4). It seems strange that they built an altar at Bethel since they had recently offered sacrifices on the one before the tabernacle there (Judges 20:26). Perhaps they rebuilt or enlarged the altar at Bethel, or they may have built another one.
