'Five' in the Bible

Now Saul's son Jonathan had a son who was crippled in both feet. He was five years old when the news about Saul and Jonathan arrived from Jezreel. His nurse picked him up and fled, but in her haste to get away, he fell and was injured. Mephibosheth was his name.

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