Giants are abnormally tall and powerful beings, that actually inhabited the earth in biblical times. There are also mythical giants found in Roman, Greek, and other mythologies. In modern times, persons well above normal height and size, and who excell in brute strength, giants if you will, are often seen in side shows, and are considered freaks of nature.
From time to time, archelogical sites have revealed bones of extinct monsters which show every indication of human origin, as evidenced in one case by a 19-foot skeleton which was unearthed at Lucerne in 1577. In 1456 and again in 1613, human remains were discovered near the Rhone which measured 30-feet in length. Imagine a being 30-feet tall towering over a normal size human of today.
Of at least six references to giants, Goliath, is probably the best known, though the only mention made of him is his appearance as the champion of the Philistines, and his death at the hands of David (I Samuel 17), in circa 1010 B.C. Goliath standing someplace between 9-feet/9-inches and 11-feet/3inches over David looked down mockingly as David said, "This day will the Lord deliver thee into mine hand," whereupon David smote the giant in the forehead with a single stone from his sling shot. As Goliath lay dead on the ground, David cut off the giant's head.
Is Goliath, and his brother who was also a giant, a myth or Biblical fact? Skeletons recovered in Palestine attest the fact that men as tall as Goliath once lived in the historical reliability of the David-Goliath narrative, adducing contradictions in the account.
The biblical Nephilim giants were the sons of Anak. These giants were fallen ones or monsters of mixed human and angelic birth, not unlike the rebellious Titians of Green mythology. They were exceedingly wicked and displayed such a violent nature that all of their thoughts were evil. Accounts of the Nephilim giants can be found in Genesis 6:4-5 and Numbers 13:33.
