'Arms' in the Bible

When he came to Lehi, the Philistines shouted as they met him: and the Spirit of Yahweh came mightily on him, and the ropes that were on his arms became as flax that was burnt with fire, and his bands dropped from off his hands.

So Delilah took new ropes, and bound him therewith, and said to him, "The Philistines are on you, Samson!" The ambush was waiting in the inner room. He broke them off his arms like a thread.
