'Bands' in the Bible

And this one was still talking when another came, and said, The Chaldaeans made themselves into three bands, and came down on the camels and took them away, putting the young men to the sword, and I was the only one who got away safe to give you the news.

The camel-trains of Tema were searching with care, the bands of Sheba were waiting for them:

When I made the cloud its robe, and put thick clouds as bands round it,

Are the bands of the Pleiades fixed by you, or are the cords of Orion made loose?

Who has let the ass of the fields go free? or made loose the bands of the loud-voiced beast?
