'Five' in the Bible

Jonathan, Saul’s son, had a son whose feet were crippled. He was five years old when the news [of the deaths] of Saul and Jonathan came from Jezreel. And the boy’s nurse picked him up and fled; but it happened that while she was hurrying to flee, he fell and became lame. His name was Mephibosheth.

So the king took the two sons of Rizpah the daughter of Aiah, whom she bore to Saul, Armoni and Mephibosheth, and the five sons of Merab the daughter of Saul, whom she had borne to Adriel the son of Barzillai the Meholathite.
