Leviticus 7:12-15
12 If he presents it for thanksgiving, in addition to the thanksgiving sacrifice,(a)(A) he is to present unleavened cakes(B) mixed with olive oil, unleavened wafers(C) coated with oil, and well-kneaded cakes of fine flour mixed with oil.
13 He is to present as his offering cakes of leavened bread(b) with his thanksgiving sacrifice of fellowship.
14 From the cakes he must present one portion of each offering as a contribution(D) to the Lord. It will belong to the priest who sprinkles the blood of the fellowship offering; it is his.
15 The meat of his thanksgiving sacrifice of fellowship must be eaten on the day he offers it;(E) he may not leave any of it until morning.(F)

Leviticus 7:12: The thanksgiving sacrifice is the first of three kinds of fellowship sacrifices. It was given to express gratitude to God (Jr 33:11) in circumstances such as answered prayer (Ps 50:14-15) or safe travel (Ps 107:22-25).
b.
Leviticus 7:13: Although yeast was prohibited from being burned on the altar (Lv 2:11), leavened bread could still be an offering (Lv 23:17-20) to be eaten by the priests and their families.
