1 Samuel 16&17 –The weight of Goliaths armor was about 125 pounds, head of his spear 16 pounds. 2023

1 Sam 17:4
Then a champion came out from the armies of the Philistines named Goliath, from Gath, whose height was six cubits and a span.

The height of Goliath has been greatly discussed. If a cubit is about 17.5 inches and a span is about half that, then Goliaths height was about nine and a half feet tall. A man being that tall is not unheard of in history. Josephus mentions a Jew, named Eleazar, whom Vitellius sent to Rome, who was seven cubits, or ten feet two inches high. Johannes Goropius Becanus (1519-1572), a Dutch physician, reported that a youth almost nine feet tall and a woman about ten feet tall lived near his home. John Middleton (1578-1623) was an English giant commonly known as the Childe of Hale. Most of what is known about him is based on oral tradition and legends. John Middleton was born in the village of Hale, near Liverpool. According to contemporary accounts and his epitaph, Middleton grew to the height of "9 feet, 3 inches" (280 centimeters), which may or may not have been accurate. Legend tells that he slept with his feet out of the window of his small house. Tales also credit him with great strength. Because of his size, landlord and sheriff of Lancashire Gilbert Ireland hired him as a bodyguard. When King James I stopped by in 1617 to knight Ireland, he also heard about Middleton and invited both of them to the court, which they accepted in 1620. In London, the King presented Middleton with a dress of purple, red and gold. Brasenose College at Oxford has a portrait of Middleton in this dress and the painted outline of his hand. Middleton beat the King's champion in wrestling and received 20[1], a large amount of money in those times. However, when Middleton was returning to Hale, his travelling companions stole the money.

John Middleton died 1623. He was buried in the Hale churchyard with an epitaph, "Here lyeth the bodie of John Middleton the Childe of Hale. Nine feet three." There is a pub in Hale, called "The Childe of Hale", which commemorates Middleton. Robert Pershing Wadlow (February 22, 1918 July 15, 1940) is the tallest person in medical history for whom there is irrefutable evidence. He is often known as the "Alton Giant" because of his Alton, Illinois hometown. Wadlow reached an unprecedented 8 feet 11.09 inches (2.72 m) in height and weighed 440 pounds (199 kg) at his death. His great size and his continued growth in adulthood was due to hypertrophy of his pituitary gland which results in an abnormally high level of human growth hormone. He showed no indication of an end to his growth even at the time of his death. There is a list on Wikipedia of 45 men and women who had gigantism. There are twelve people in recorded medical history to reach or surpass eight feet in height. Considering the nutritional value of the food grown in the "land flowing with milk and honey" the height of nine and a half feet is not unreasonable.

And he had a bronze helmet on his head, and he was clothed with scale-armor which weighed five thousand shekels of bronze.
