I can’t wrap my brain around the Nephilim. I guess it explains Goliath.

[Hebrews 11:6]

Goliath and his brother were two of the shorter ones. King Og had the famous 13' iron bed.

There is a raging debate whether "angels who did not keep their positions of authority but abandoned their proper dwelling—these he has kept in darkness, bound with everlasting chains for judgment on the great Day" (Jude 6) mated with human women to produce the Nephilim, variously called "Rephaim" and "Anakim."

Aside from their enormous size and strength (Goliath's armor weighed 250 pounds), these other features argue for supernatural origin: persistent polydactylism (extra fingers and toes), exclusively male, and normal agility despite their size (humans above 8' are typically infirm).

[Hebrews 11:6]

Actually, aside from the picture you posted I’ve found very few works representing biblical nephilim, along with hundreds of fantastical/demonic offerings by occultish apocalyptic nincompoops. Whatever Goliath images there are must await our arrival at David’s little tete-a-tete with him.
