The Angel Raziel was voiced by actor Anthony Head, who is probably best known for playing Giles in another popular vampire fantasy series, "Buffy the Vampire Slayer."
The episode was shot together with the nineteenth episode, though the episodes were still released separately. Filming ended on May 9, 2017.
The title of the episode refers to Psalm 23:2, not to the Lord's Prayer (as some have suggested).
This is the last episode to credit Alisha Wainwright as a guest star. From the next episode onwards she is a series regular.
