'Infantry' in the Bible

I did this because I was ashamed to ask the king for infantry and cavalry to protect us from enemies during the journey, since we had told him, “The hand of our God is gracious to all who seek Him, but His great anger is against all who abandon Him.”

I went to the governors of the region west of the Euphrates and gave them the king’s letters. The king had also sent officers of the infantry and cavalry with me.
