I might think to exclude sin and gift-offerings; it is, therefore, written "your consecrated things."
And who "whispered" to you to include sin and gift-offerings and to exclude bechor and ma'aser? After Scripture includes (i.e., "your consecrated things"), it excludes (i.e., only "your vows"). I include sin and guilt-offerings, which can be eaten only in their place (the Temple), and I exclude bechor and ma'aser, which can be eaten in all places.
R. Akiva says: Scripture (i.e., "your consecrated things") speaks of a substitute (for an offering). "you shall bear and you shall come": I might think even a bechor and ma'aser; it is, therefore, written "and your vows." Ben Azzai says: Scripture (i.e., "your consecrated things") speaks only of your holy things of the beast tithe.
