'Infantry' in the Bible

Elam took up the quiverWith the chariots, infantry and horsemen;And Kir uncovered the shield.

They will come against you with weapons, chariots, and wagons, and with a company of people (infantry) who will array themselves against you on every side with large shield and small, and helmet; and I will commit the judgment and the punishment to them, and they will judge and punish you in accordance with their [pagan] customs.
