I found this passage fascinating and did some research on it. I found a paper from  US National Library of Medicine
National Institutes of Health

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4113151/ here is the link to the paper. The paper explains how giants in the Bible can be scientifically explained through genetics. Very interesting read. The abstract of the paper reads:

“The biblical giant Goliath has an identifiable family tree suggestive of autosomal dominant inheritance. We suggest that he had a hereditary pituitary disorder possibly due to the AIP gene, causing early onset and familial acromegaly or gigantism. We comment on the evidence within the scriptures for his other relatives including a relative with six digits and speculate on possible causes of the six digits. Recognition of a hereditary pituitary disorder in the biblical Goliath and his family sheds additional information on his and other family members’ battles with David and his relatives.”

I will make a much larger post about Giants in the Bible soon.
