a coat of scale armor: a shirt faced with rows of small overlapping metal or leather plates, worn to protect the body in battle
A shiryon was not a sheet of metal but a garment. Rows of small plates, called scales, were sewn onto a backing of leather or heavy cloth so that each row overlapped the one below it. The result bent with the body like a shirt while still turning a blade or an arrow. Coats like this, and loose scales from them, have been dug up all across the ancient Near East, and one made of leather survived in Tutankhamun's tomb, built from layers of linen faced with more than four thousand rawhide scales.
The word almost certainly came into Hebrew from somewhere else. Nearly identical words for the same coat turn up in Babylonian, Ugaritic, and Egyptian records, spreading through the region along with chariot warfare, and the odd ending on the Babylonian form is the giveaway that it was not homegrown there either. Scholars still argue over which language it started in, but they agree Hebrew borrowed it rather than built it from a root of its own.
Every occurrence names the same object, and the uses run from hardware to poetry:
- Goliath wears one of bronze scales, and Saul lends his own coat to David.
- An arrow slips through a seam in Ahab's coat and kills him in his chariot.
- Uzziah stocks a whole army with them, and Nehemiah's guards keep them at hand.
- The Lord puts righteousness on like one, matched with a helmet (כּוֹבַע) of salvation.
That last picture had a long afterlife. Greek translators regularly reached for their own word for a breastplate (θώραξ) to render this coat, and Isaiah's line about righteousness worn as armor comes through in the New Testament as the breastplate of righteousness.
