Musar su Esodo 12:25

Now we can get back to our main subject, the עבודה, service, which is mentioned in this portion many times, and the reason why the Torah repeats the warning to observe this service. We must understand why this paragraph repeats: "You shall be careful to observe this statute from year to year." Although I have written at some length about the importance of עבודה when discussing the meaning of שובבים ת"ת on page 386, I shall explain a number of verses in our portion in which עבודה is stressed. He (Pharaoh) said to them go and serve the Lord your G–d" (10,8). Or, in verse 24: עבדו את ה' רק צאנכם ובקרכם יצג, גם טפכם ילך עמכם, "Go and serve the Lord; only your flocks and cattle will remain; your children may go with you." Moses replied: "You too will give us various kinds of offerings which we will sacrifice to the Lord our G–d; our cattle will go with us, not a hoof will remain behind, for from it we will take to serve, לעבוד the Lord our G–d; we do not know how we shall serve, נעבוד the Lord our G–d until we get there."
