'Guards' in the Bible

Meanwhile, down in Egypt, the Midianites sold Joseph to Potiphar, one of Pharaoh's court officials, who was also Commander-in-Chief of the imperial guards.

Meanwhile, Joseph had been delivered to Egypt and turned over to Potiphar, one of Pharaoh's court officials and the Commander-in-Chief of the imperial guards. An Egyptian, he bought Joseph from the Ishmaelites, who had brought him down there.

Pharaoh was enraged with his servants, and he put me in prison in the house of the captain of the guards -- me and the chief baker.

Now a young Hebrew, a slave of the captain of the guards, was with us there. We told him our dreams, he interpreted our dreams for us, and each had its own interpretation.
