'Captain of the Guard' in the Bible

He put them in confinement in the house of the captain of the guard, in the same prison where Joseph was confined.

The captain of the guard put Joseph in charge of them, and he served them; and they continued to be in custody for some time.

[Two years ago] Pharaoh was angry with his servants, and he put me in confinement in the house of the captain of the guard, both me and the chief baker.

Now there was with us [in the prison] a young man, a Hebrew, servant to the captain of the guard; and we told him, and he interpreted our dreams for us, to each man according to the significance of his own dream.
