'Buckler' in the Bible

Thy daughters in the field by sword he slayeth, And he hath made against thee a fort, And hath poured out against thee a mount, And hath raised against thee a buckler.

And I have turned thee back, And I have put hooks in thy jaws, And have brought thee out, and all thy force, Horses and horsemen, Clothed in perfection all of them, A numerous assembly, with buckler and shield, Handling swords -- all of them.

And gone out have the inhabitants of cities of Israel, And they have burned and kindled a fire, With armour, and shield, and buckler, With bow, and with arrows, And with hand-staves, and with javelins, And they have caused a fire to burn with them seven years,
