2 Samuel 20:21

A man of Mount Ephraim. Quest. How can this be so when he is called a Benjamite, 2 Samuel 20:1 ? Answ. Either he was a Benjamite by birth, but dwelt in the tribe of Ephraim, as many did upon several occasions dwell out of their own tribes; or Mount Ephraim was a place in Benjamin, which might be so called, either because it was upon the borders of Ephraim, and looked towards it; or from some notable action or event of the Ephraimites in that place. Compare 1 Samuel 18:6. Hath lift up his hand, i.e. taken up arms, or raised rebellion.

And it is not unlikely that this woman might be a governess in that city for though this office was commonly performed by men, yet were not the women wholly excluded, but sometimes employed in the government; as we see in Deborah, who judged Israel, Judges 4:4; and queen Athaliah, 2Ki 11.
