The people of Afriki claimed Canaan from the Israelites before Alexander. Gaboha, son of Pesisa pleaded their cause and he proved that Canaan having been declared a slave (Gen. 9, 25) the people belong to the master. He claimed on the contrary the amount of labour due which they had not rendered to the Israelites for so many years before the Israelites entered the land. They gave no reply after grace of three days and then left the country.
