The answer
Numbers 13:33. Israelite spies scouting Canaan report: "There we saw the Nephilim… and to ourselves we seemed like grasshoppers." Genesis 6:4 had already hinted at this — the Nephilim were on the earth "in those days — and also afterward."
Why it’s interesting
How figures from before the flood appear in a report centuries after it is a question the text never addresses — though the narrative itself calls the spies' account "an unfavorable report." Readers have puzzled over the word "afterward" for a very long time.
