'Ten' in the Bible

So he [obeyed and] went away and began to publicly proclaim in Decapolis [the region of the ten Hellenistic cities] all the great things that Jesus had done for him; and all the people were astonished.

Soon after this Jesus left the region of Tyre, and passed through Sidon to the Sea of Galilee, through the region of Decapolis [the ten Hellenistic cities].

Hearing this, the [other] ten became indignant with James and John.
