2 Corinthians 11:26
“In perils of rivers.”
For he was compelled also to cross rivers. “In perils of robbers, in perils in the city, in perils in the wilderness.” 'Everywhere were contests set before me, in places, in countries, in cities, in deserts.'
“In perils from the Gentiles, in perils among false brethren.”
Behold another kind of warfare. For not only did such as were enemies strike at him, but those also who played the hypocrite; and he had need of much firmness, much prudence.
