Arithmeo describes counting or being counted, whether every hair is included or a great crowd cannot be counted.

The attested passages show counting as the inclusion of individual items—hair by hair—and, in contrast, as an action no one can accomplish for a great crowd.

   In Luke 12:7 and Matthew 10:30, perfect passive forms occur with the hairs of the head; the APB renders the clause "the hairs of your head are all numbered." In Revelation 7:9, an aorist active infinitive occurs in the statement that no one was able to count the great crowd; the APB renders it "a great crowd that no one was able to number."

In the Anselm Project Bible: The APB presents the passive clauses in Luke 12:7 and Matthew 10:30 as "numbered" and the active infinitive in Revelation 7:9 as "to number." These are renderings of the verse clauses rather than definitions.
