There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown. (Genesis 6:1-4)
When people think of giants in the Bible, they generally think of Goliath. As in David, Goliath and the “slingshot”.
Goliath was both big and tall. But they wouldn’t carry his size in the “big men’s” department at J.C. Penny’s. He was about 13 feet tall, if I remember correctly.
Now, granted, that’s huge. But I’m thinking about guys a whole lot bigger than that.
