2 Samuel 20:21

“The matter [is] not so, etc.] I am not come with the army against this city with any ill will to it, and with an intention to destroy it: the case is this, but a man of Mount Ephraim, Sheba the son of Bichri by name; for though he was by birth a Benjaminite, his dwelling was in Mount Ephraim in that tribe; unless there was a place of this name in the tribe of Benjamin, so called from any memorable event there, as the wood of Ephraim, (<101806>2 Samuel 18:6). This same man, says Joab, hath lifted up his hand against the king, [even] against David; is in rebellion against the king, even so great and good a king as David; he has lifted up his hand, and blown a trumpet to draw off men from…”

“Ephraim - Probably mount Ephraim was a place in Benjamin so called, either because it was upon the borders of Ephraim or for some notable action or event of the Ephraimites in that place. His head - Which she undertook, because she knew the present temper of the citizens, and soldiers too. And it is not unlikely, that this woman might be a governness in that city. For though this office was commonly performed by men; yet women were sometimes employed in the government: as we see in Deborah, who judged Israel, Jdg 4:4. 2 Kings (2 Samuel) 20:22”

“a man: Sa2 20:1; Jdg 2:9, Jdg 7:24; Kg2 5:22; Jer 4:15, Jer 50:19 by name: Heb. by his name lifted: Sa2 23:18; Sa1 24:6, Sa1 26:9 his head: Sa2 17:2, Sa2 17:3; Kg2 10:7; Jdg 18:4-8 2 Kings (2 Samuel) 20:22”
