Exodus 5:15

“Then the officers of the children of Israel came and cried unto Pharaoh, etc.] Made their complaints to him, perhaps with tears in their eyes, being used so very ill. They little thought it was by Pharaoh’s orders; they supposed he knew nothing of it, and therefore hoped to have their grievances redressed by him, but were mistaken: saying, wherefore dealest thou thus with thy servants? so they call themselves, they living in his country, and being under his jurisdiction, though not properly his subjects; however, he had made them his slaves, and so indeed even bondservants.”
