This ordinal number indicates position in sequence (the tenth item) or proportion (a tenth part, tithe). Classical usage includes both ordinal and fractional senses. In John's Gospel, it marks the 'tenth hour' of the day when Andrew and another disciple followed Jesus. Revelation uses it to describe the 'tenth part' of the city that fell in the earthquake and the tenth foundation stone in the New Jerusalem's walls. The term can carry theological weight when referring to tithes, though that sense doesn't appear in these New Testament occurrences.
