Perizzites - villagers; dwellers in the open country, the Girgashite Canaanitish nation inhabiting the fertile regions south and south-west of Carmel. "They were the graziers, farmers, and peasants of the time." They were to be driven out of the land by the descendants of Abraham (Gen. 15:20; Ex. 3:8, 17; 23:23; 33:2; 34:11). They are afterwards named among the conquered tribes (Josh. 24:11). Still lingering in the land, however, they were reduced to servitude by Solomon (1 Kings 9:20).
Perizzites are cripples, lame people who feel unworthy, who feel spiritually unable to walk on their own.
As spiritual cripples, Perizzite believers refuse to "walk", and prefer to delegate spiritual judgments to those whom they believe to be more worthy of such an honor than their "tiny" and "insignificant" selves.
Perizzite believers are unaware of their spiritual authority to judge, and therefore are to God as spiritual cripples, unable to walk in His judgments and unable to establish God's kingdom authority on Earth.
