И сказал Моисей: 'Ты также должен приносить в наши руки жертвы и всесожжения, чтобы мы могли приносить жертвы Господу, нашему Богу.

Really now? [We know celebration refers to sacrificing] for it is written (Exodus 5:1) "That they may celebrate unto Me in the wilderness"! Indeed, that refers to celebrating as a festival. But you'll say it does indeed [mean that], but it is written (Exodus 10:25) "But Moses said, 'You must also let us have sacrifices and burnt offerings, that we may sacrifice to God our God.'" [Obviously, the "celebration was the sacrifices indicated here!]
