2 Samuel 18:6

“So the people went out into the field against Israel, etc.] Josephus f303 calls it a great field, with a wood behind it: and the battle was in the wood of Ephraim; or near it f304 rather; not in a wood in the tribe of Ephraim, which lay on this side Jordan; whereas this battle was fought on the other side Jordan, in the land of Gilead, not far from Mahanaim, where was this wood; and which was so called, either from the slaughter of the Ephraimites here in the times of Jephthah, (<071204>Judges 12:4-6); or from the Ephraimites feeding their cattle here and near it; for the Jews say f305, that Joshua gave them a grant to feed their cattle in any wood in any of the tribes of Israel; and lying…”

“wood of Ephraim--This wood, of course, was on the east of Jordan. Its name was derived, according to some, from the slaughter of the Ephraimites by Jephthah--according to others, from the connection of blood with the trans-jordanic Manasseh.”

“Against Israel - Implying that the revolt was in a great measure that of the ten tribes, Saul’s party, against the kingdom. The wood of Ephraim - This would naturally be sought in the west of Jordan (marginal reference). But on the other hand it seems certain that the scene of this battle was on the east of Jordan. It seems therefore inevitable to conclude that some portion of the thick wood of oaks and terebinths which still runs down to the Jordan on the east side was for some reason called “the wood of Ephraim,” either because it was a continuation on the east side of the great Ephraimitic forests on the west, or because of some transaction there in which Ephraim had taken part, such as…”

“wood of Ephraim: The wood of Ephraim was evidently beyond Jordan, and apparently not far from Mahanaim; and it is supposed to be the place where the Ephraimites were slain by Jephthah. Jos 17:15, Jos 17:18; Jdg 12:4-6 2 Kings (2 Samuel) 18:7”

“Battle in the wood of Ephraim, and death of Absalom. - Sa2 18:6, Sa2 18:7. When the people, i.e., David's army, had advanced into the field against Israel (those who followed Absalom), a battle was fought "in the wood of Ephraim," when Israel was smitten by David's warriors and sustained a loss of 20,000 men. The question, where the "wood of Ephraim" was situated, is a disputed one. But both the name and the fact that, according to Jos 17:15-16, the tribe-land of Ephraim abounded in forests, favour the idea that it was a wood in the inheritance of Ephraim, on this side of the Jordan; and this is in perfect harmony with the statement in Sa2 18:23, that Ahimaaz took the way of the Jordan…”
