'Arm' in the Bible

Peoples will be in fear before his strength, his arm will be on great nations: his king will be higher than Agag, and his kingdom made great in honour.

And we have here an offering for the Lord from what every man took in the war, ornaments of gold, leg-chains and arm-rings, finger-rings, ear-rings, and neck-ornaments, to make our souls free from sin before the Lord.
