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.
Omrides
Israel Finkelstein's "The Bible Unearthed" presents a very different picture of the Omrides, making them responsible for the great empire, magnificent palaces, wealth, and peace in Israel and Judah that the Bible credits to the much earlier kings David and Solomon. According to Finkelstein, the reason for this discrepancy is the religious bias of the Biblical authors against the Omrides for their polytheism, and in particular their support for elements of the Canaanite religion.
