In August 1934, the Nazi government enacted a law implementing a new Reichswehr oath:

Article One

Civilian officials and soldiers of the Armed Forces must take an oath of service on entering the service.

Article Two

1. The oath of service of civilian officials will be:

“I swear: I shall be loyal and obedient to Adolf Hitler, the Führer of the German Reich and people; respect the laws; and fulfil my official duties conscientiously, so help me God.”

2 The oath of service of the soldiers of the Armed Forces will be:

“I swear by God this sacred oath, that I will render unconditional obedience to Adolf Hitler, the Fuhrer of the German Reich and people, supreme commander of the Armed Forces, and will be ready as a brave soldier to risk my life at any time for this oath.”
