I LOVE LEARNING! Adam: “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. Cleave: 1. To adhere, cling, or stick fast. 2.To be faithful: cleave to one's principles i'm thinking about reading the Bible.
