(Bamidbar 28:9) "And on the Sabbath day, two lambs of the first year without blemish": It is written "The one lamb shall you offer in the morning," and the (tamid of the) Sabbath is included in that. Scripture (here) removes it from its (merely) general category for (purposes of) stringency, (i.e., the fixed (additional ["mussaf"] offering). Variantly: From (Vayikra 26:2) "My Sabbaths you shall keep and My sanctuary you shall fear" it is deduced that the sacrificial service overrides the (keeping of the) Sabbath.
You say this, but perhaps (the meaning is that) the Sabbath overrides the sacrificial service? From "And on the Sabbath day, two lambs of the first year, etc." we find the meaning of the above to be that the sacrificial service overrides the Sabbath. — But perhaps both individual and communal offerings (override it)? What is the context (of "And on the Sabbath day")? Communal offerings, (so that only communal and not individual offerings override the Sabbath.)
