דן גור אריה DAN IS A LION’S CUB — He, too, lived close to the border, and therefore it compares him to a lion (Sifrei Devarim 355:12).

גור אריה יזנק מן הבשן. Actually, lions do not grow up in Bashan, a land reserved for cattle, as we know from Psalms 22,13 אבירי בשן, “the mighty ones (bulls) of Bashan.” Lions, as predators do not lie in wait to jump on their prey there. They would only lie in wait in Bashan, a region considered safe from predators, if they planned to attack prey beyond the borders of Bashan. The tactics of the tribe of Dan are compared by Moses to the tactics of the lions. Dan will feel secure in his lair from which he will attack unsuspecting adversaries.

גור אריה, "a lion cub, etc." Perhaps the Torah referred to Samson who tore the lion with his bare hands as if it had been only a lamb (Judges 14,6). יזנק מן הבשן, "leaping forth from Bashan." This is a reference to the Holy Spirit with which Samson was endowed when he performed his deeds of valour. It made him appear as if he leapt out of the mountains of Bashan.
