It depends you could say you have to be on the bed, or you have to be in bed. If you are referring to having to be asleep at or having a bedtime, the correct form is "have to be in bed"
bed
This is how you say get on bed in Russian: Lajis na pastel=get on bed. I hope I helped you :)

bed in french would be être.
"Go to bed"
