Acts 21:9 Now this man had four virgin daughters who prophesied.
Why would God choose virgin daughters to be prophets?
Society at that time was all about what men did and said. So, God chose women instead.
Society looked up to what the elders did and said because they should know with experience. So, God chose daughters instead.
They probably had more of an open heart than all the other leaders because they were listening to God and not man. God knows exactly what He is doing!
