מדרש על שמות 29:28

1) Or, (this binyan av) adduces (the tenufah-haramah identity) only for what is similar to it (the miluim [investiture] ram [viz.: Shemoth 29:27]). (That is,) just as this (investiture offering) is a sturdy, two-year-old ram and requires bread, so (the binyan av applies only to a thanksgiving ram [similar to the miluim ram]), sturdy, two years old, and requiring bread. Whence do I derive (that it applies also to an offering that is) "sturdy" and does not require bread (i.e., a peace-offering ram); to one that is "soft" and requires bread (i.e., a one-year-old thanksgiving lamb); and to one that is soft and does not require bread (a peace-offering lamb)? — until you include "cattle, lambs, and goats" (that obtained at the miluim)? From (Shemoth 29:28): "For it is terumah and terumah shall it be from the children of Israel from the sacrifices of their peace-offerings, their terumah to the L–rd" — to include all of them (in the tenufah-haramah identity).
