And don't forget to kneel before Me.
How is it a command, if all commands in Spanish end in "a?" I understand that "Se arrodilla ante Zod" does also mean "He/she kneels before Zod," but I was taught that commands end in "a", and the difference between that and the el/ella/usted form was none, and that you had to look at the context.
