The word "hest" is an old-fashioned term that means "command" or "order." It's often used in literature and historical texts to describe a powerful person's actions or a military authority's instructions. However, if you're looking for a more modern synonym, you might try "directive," "injunction," or "decree." These words all convey a similar sense of authority and command, but they are more commonly used in contemporary English. Additionally, you could use "instruction," "demand," "requirement," or "mandate" to express the same idea. Whether you're writing a formal document or a creative work, it's always useful to have a variety of synonyms at your disposal.
