Not alone Sihon and Og, the kings of the Amorites, were such giants and heroes, but all the Amorites. When Hadrian conquered Jerusalem, he boasted of his victory, whereupon Rabba Johanan, the son of Zakkai, said to hi: "Boast not of thy victory over Jerusalem, for, had not God conquered it for thee, thou shouldst never have gained it." He thereupon led Hadrian to a cave where he showed him the corpses of the Amorites, each of which was eighteen cubits, and said: "When we were worthy of victory, these fell into our hands, but now, on account of our sins, dost thou rule over us."
