     Then said he to another, And how much owest thou? And he said, An hundred measures of wheat. And he said unto him, Take thy bill, and write fourscore. (KJV)

This number is a noun; as such, the entities being counted are in the genitive case.

In Luke 2:37 one would expect a genitive *𐌰𐌷𐍄𐌰𐌿𐍄𐌴𐌷𐌿𐌽𐌳𐌹𐍃 (*ahtautēhundis), but the base form 𐌰𐌷𐍄𐌰𐌿𐍄𐌴𐌷𐌿𐌽𐌳 (ahtautēhund) is found instead, suggesting that the word was not always declinable. See also 𐌽𐌹𐌿𐌽𐍄𐌴𐌷𐌿𐌽𐌳 (niuntēhund).
