‘Then at the beginning of each of your months you shall present a burnt offering to the LORD: two bulls and one ram, seven male lambs one year old without defect

You shall present an offering by fire, a burnt offering to the LORD: two bulls and one ram and seven male lambs one year old, having them without defect.

‘Also on the day of the first fruits, when you present a new grain offering to the LORD in your Feast of Weeks, you shall have a holy convocation; you shall do no laborious work.
