Definition: Verse 5: "For he shall be a shield to the upright man; and his feet shall bring him safely over the rivers of water." Armlets were pieces of metal that covered the upper part of the arms, often made of bronze or wrought iron, worn by soldiers to protect them against injury. They served as shields, and some even as weapons, during battles. The term "armlets" is used metaphorically in this verse to mean protection, especially a shield.
