'Scale armor' in the Bible

He had a bronze helmet on his head, and he was clothed with scale-armor which weighed five thousand shekels of bronze.

“Harness the horses,And mount the steeds,And take your stand with helmets on!Polish the spears,Put on the scale-armor!

“Let not him who bends his bow bend it,Nor let him rise up in his scale-armor;So do not spare her young men;Devote all her army to destruction.
