'Princes' in the Bible

And the princes of Pharaoh saw her, and praised her to Pharaoh: and the woman was taken into Pharaoh's house.

And as for Ishmael, I have heard thee: behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation.

These are the sons of Ishmael, and these are their names, by their villages, and by their encampments. Twelve princes according to their nations.
