'Masters' in the Bible

Then God said, "Let us make mankind in our image, to be like us. Let them be masters over the fish in the ocean, the birds that fly, the livestock, everything that crawls on the earth, and over the earth itself!"

God blessed the humans by saying to them, "Be fruitful, multiply, fill the earth, and subdue it! Be masters over the fish in the ocean, the birds that fly, and every living thing that crawls on the earth!"

And he said, My masters, come now into your servant's house and take your rest there for the night, and let your feet be washed; and early in the morning you may go on your way. And they said, Not so, but we will take our night's rest in the street.
