Goliath
Goliath is described in the biblical Book of Samuel as a Philistine giant defeated by the young David in single combat. The story signified Saul's unfitness to rule, as Saul himself should have fought for the Kingdom of Israel.
Dinah
This portion of the Book of Genesis deals primarily with the family of Abraham and his descendants, including Dinah, her father Jacob, and her brothers. The traditional view is that Moses wrote Genesis as well as almost all the rest of the Torah, doubtlessly using varied sources but synthesizing all of them together to give the Hebrews a written history of their ancestors. This view—which has been held for the past several thousand years, although it is not explicitly mentioned in either the Hebrew or the Christian Bible—holds that Moses included this story primarily because it happened and he viewed it as significant. It foreshadows later happenings and prophecies further along in Genesis and the Torah dealing with the two violent brothers.
