A third woman who is mentioned in the Old Testament as being a well-respected prophetess is Huldah. God used her to give reliable prophetic insight and instruction to a man, the troubled king of Judah, Josiah (see 2 Kin. 22). Again we see an example of God using a woman to instruct a man. Most likely, Huldah was used by God in such a ministry with some degree of regularity, otherwise Josiah would not have had such faith in what she said to him.
But why did God call Miriam, Deborah and Huldah as prophetesses? Couldn’t He have called men instead?
Certainly God could have called men to do exactly what those three women did. But He didn’t. And no one knows why. What we should learn from this is that we had better be careful about putting God in a box when it comes to whom He calls to ministry. Although God normally chose men for leadership tasks in the Old Testament, sometime He chose women.
Finally, it should be noted that all three preeminent examples of female ministers in the Old Testament were prophetesses. There are some Old Testament ministries to which no women were called. For example, there are no women who were called to be priests. Thus God might reserve some ministry offices exclusively for men.
