Genesis 4 tells of the birth of Cain and Abel, Adam and Eve's first children, while Genesis 5 gives Adam's genealogy past that. Adam and Eve are listed as having three children, Cain, Abel and Seth, then "other sons and daughters", Genesis 5:4. https://www.google.com.ng/url?sa=t&source=web&rct=j&url=%23&ved=0ahUKEwiS8a-0n4nYAhXIHxoKHYr2CeMQwqsBCEcwBA&usg=AOvVaw0VTJzWxrN8ZFOD4xbU2nov
