Genesis Chapter One
Genesis 1:26-27
And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth. So God created man in his own image, in the image of God created he him; male and female created he them.
Genesis Chapter Two
Genesis 2:7
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 soul.
Genesis 2:21-24
And the LORD God caused a deep sleep to fall upon Adam, and he slept: and he took one of his ribs, and closed up the flesh instead thereof; And the rib, which the LORD God had taken from man, made he a woman, and brought her unto the man. And Adam said, This is now bone of my bones, and flesh of my flesh: she shall be called Woman, because she was taken out of Man. Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.
New Testament
Matthew 19:4-6
And he answered and said unto them, Have ye not read, that he which made them at the beginning made them male and female [Genesis chapter 1], And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh [Genesis chapter 2]? Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder.
Mark 10:6-9
But from the beginning of the creation God made them male and female [Genesis chapter 1]. For this cause shall a man leave his father and mother, and cleave to his wife; And they twain shall be one flesh [Genesis chapter 2]: so then they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder.
