'Burnt offerings' in the Bible

All the animals for the burnt offerings were twelve bulls, the rams twelve, the lambs of the first year twelve, with their food offering. And the males of the goats for a sin offering twelve.

Also in the day of your gladness, and in your solemn days, and in the beginnings of your months, you shall blow with the trumpets over your burnt offerings, and over the sacrifices of your peace offerings. And they shall be to you for a memorial before Jehovah. I am Jehovah your God.

You shall prepare these to Jehovah in your appointed seasons, besides your vows and your free-will offerings, for your burnt offerings, and for your food offerings, and for your drink offerings, and for your peace offerings.
