'Arms' in the Bible

When he arrived in Lehi, the Philistines shouted as they approached him. But the Lord's spirit empowered him. The ropes around his arms were like flax dissolving in fire, and they melted away from his hands.

So Delilah took new ropes and tied him with them and said to him, "The Philistines are here, Samson!" (The Philistines were hiding in the bedroom.) But he tore the ropes from his arms as if they were a piece of thread.
