The battlefield where Absalom fell, the entanglement of the wood occasioning large slaughter of the Ephraimites, from whence perhaps the wood was named. From 2Sa 17:24,26; 18:3, it is certain that it was E. of Jordan, not W. where the tribe Ephraim was settled. Mahanaim was the "city out of" which David's army looked for "succour" from him. Grotius thinks, less probably, that the name was derived from the slaughter of Ephraim at the Jordan fords by Jephthah (Jg 12:1-5); the city Mahanaim and wood of Ephraim were miles off from the Jordan.
