Gollum
Gollum is a fictional character from J. R. R. Tolkien's legendarium. He was introduced in the 1937 fantasy novel "The Hobbit", and became an important character in its sequel, "The Lord of the Rings". Gollum was a Stoor Hobbit of the River-folk, who lived near the Gladden Fields. Originally known as Sméagol, he was corrupted by the One Ring and later named Gollum after his habit of making "a horrible swallowing noise in his throat".
Goliath
In Pseudo-Philo, believed to have been composed between 135 BC and 70 AD, David picks up seven stones and writes on them his father's name, his own name, and the name of God, one name per stone; then, speaking to Goliath, he says "Hear this word before you die: were not the two woman from whom you and I were born, sisters? And your mother was Orpah and my mother Ruth ..." After David strikes Goliath with the stone he runs to Goliath before he dies and Goliath says "Hurry and kill me and rejoice." and David replies "Before you die, open your eyes and see your slayer." Goliath sees an angel and tells David that it is not he who has killed him but the angel. Pseudo-Philo then goes on to say that the angel of the Lord changes David's appearance so that no one recognizes him, and thus Saul asks who he is.
