26 Then God said, “Let Us make man in Our image, according to Our likeness; let them have dominion over the fish of the sea, over the birds of the air, and over the cattle, over all the earth and over every creeping thing that creeps on the earth.”
27 So God created man in His own image; in the image of God He created him; male and female He created them.

And the Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living being.

28 Then God blessed them, and God said to them, “Be fruitful and multiply; fill the earth and subdue it; have dominion over the fish of the sea, over the birds of the air, and over every living thing that moves on the earth.”

29 And God said, “See, I have given you every herb that yields seed which is on the face of all the earth, and every tree whose fruit yields seed; to you it shall be for food.
30 Also, to every beast of the earth, to every bird of the air, and to everything that creeps on the earth, in which there is life, I have given every green herb for food”; and it was so.

27 So God created man in His own image; in the image of God He created him; male and female He created them.

4 What is man that You are mindful of him,
And the son of man that You visit him?
5 For You have made him a little lower than the angels,
And You have crowned him with glory and honor.
6 You have made him to have dominion over the works of Your hands;
You have put all things under his feet,

27 So God created man in His own image; in the image of God He created him; male and female He created them.

And He has made from one blood every nation of men to dwell on all the face of the earth,
