Jeremiah 46:4

Harness the horses ,.... Put on their bridles and saddles and gird them: or, "bind the horses" F18 אסרו הסוסים "ligate equos", Montanus, Calvin; "alligate", Schmidt. ; that is, to the chariots; put them to, as we commonly express it: Egypt abounded in horses, and so no doubt brought a large cavalry, and a multitude of chariots, into the field of battle:

and get up, ye horsemen ; upon the horses, or into the chariots, and so be ready to receive the enemy, or to attack him:

and stand forth with your helmets ; present themselves on horseback, or in their chariots, with their helmets on their heads, to cover them in the day of battle:

furbish the spears ; that they may be sharp and piercing, and look bright and glittering, and strike terror in the enemy:

and put on the brigandines ; coats of mail, to cover the whole body, which were made of iron, consisting of rings, as Kimchi observes.
