'Arms' in the Bible

He hath come unto Lehi -- and the Philistines have shouted at meeting him -- and the Spirit of Jehovah prospereth over him, and the thick bands which are on his arms are as flax which they burn with fire, and his bands are wasted from off his hands,

And Delilah taketh thick bands, new ones, and bindeth him with them, and saith unto him, 'Philistines are upon thee, Samson;' and the ambush is abiding in an inner chamber, and he breaketh them from off his arms as a thread.
