Some time after Adam and Eve were driven from Eden children were born to them, who grew to the estate of manhood and womanhood and they in turn had children. Cain obtained his wife by marrying his sister. Thus the peoples of earth gradually increased. They all wandered about in the earth, earning their bread in the sweat of their face. Some of these children were bad and some were good. God showed his favor to the good, as he always favors those who are good. Satan exercised his wicked influence amongst the people and most of them turned to evil. [93]Noah was a good man and he and the members of his family served the Lord Jehovah. Sixteen hundred years and more passed from the time of the judgment in Eden (during which time the people became very wicked) and there was great violence in the earth. God purposed to destroy all the wicked of earth; so he directed Noah to build an ark and to take into the ark the members of his family; and this done, a great flood of waters came upon the earth and all living creatures were destroyed except those in the ark. There were only eight persons left on the earth after the flood. (Genesis 7:21-23; 1 Peter 3:20) Noah and his sons begat children and the peoples of earth again increased. Amongst them were some good and some bad. Amongst those who tried to do the will of God was a man named Abram, which name was later changed to Abraham. He is spoken of in the Scriptures as the friend of God. Abraham's wife was named Sarah. [94]When Abraham was 75 years of age, Jehovah said to him: "Get thee out of thy country, and from thy kindred, and from thy father's house, unto a land that I will show thee: and I will make of thee a great nation, and I will bless thee, and make thy name great; and thou shalt be a blessing; and in thee shall all families of the earth be blessed". (Genesis 12:1-3) Abraham with his wife and others left Haran for the land of Canaan. When they had reached a point in that land known as Sichem, the Lord appeared unto him and said: "Unto thy seed will I give this land". Abraham builded an altar there, and the place has since been known as Bethel, which means the house of God. Afterward Abraham dwelt in the plains of Mamre, which is just above the present site of Hebron in the southern part of Palestine. While there, God made a covenant with him, saying: "Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates".--Genesis 15:18.
