'Arms' in the Bible

When he came unto Lehi, the Philistines shouted as they met him: and the Spirit of Jehovah came mightily upon him, and the ropes that were upon 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 unto him, The Philistines are upon thee, Samson. And the liers-in-wait were abiding in the inner chamber. And he brake them off his arms like a thread.
