2.61

爾時眾中有百億人，即從坐起受持佛戒，其名梵陀首王，共無數天子修十戒滿足，入初住位。

At that time, there were ten billion people in the assembly who immediately rose from their seats and received and maintained the Buddha's precepts; their leader was King Brahmadatta, who together with countless devaputras fulfilled the cultivation of the ten precepts and entered the stage of the first abode.
