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.
Daniel (biblical figure)
The Book of Daniel begins with an introduction telling how Daniel and his companions came to be in Babylon, followed by a set of tales set in the Babylonian and Persian courts, followed in turn by a set of visions in which Daniel sees the remote future of the world and of Israel. The tales in chapters 1–6 can be dated to the 3rd or early 2nd centuries BCE; it is generally accepted that these were expanded by the addition of the visions in chapters 8–12 between 167 and 164 BCE.
