Then he threw him (auton | αὐτόν | acc sg masc3rd) into the abyss, locked and sealed it over him (autou | αὐτοῦ | gen sg masc3rd), so he could not deceive the nations any longer, until the thousand years were finished. After that he (auton | αὐτόν | acc sg masc3rd) must be set loose for a short time.
