I. [‎לָחַם‎]171 verb fight, do battle (Late Hebrew Hithpa`el; ‎ואלתחם‎ MI11.15.19 perhaps = order the battle, compare ZMG xl. 1886, 721; Arabic fit close together, so Late Hebrew ‎לחם‎ Pi`el, Syriac Pa`el unite, fit also threaten; GerberVerb. Denom. 59 thinks verb in Hebrew denominative from ‎מִלְחָמָה‎ battle-line, but dubious); —
