Offal

The internal organs of an animal, traditionally regarded as being inferior to meat, and used as a symbol of disgrace.

Offal is symbolic of disgrace

Malachi 2:3 See also Nahum 3:6

Behold, I will rebuke your descendants, and I will spread dung on your faces, the waste from your feasts, and you will be carried off with it.

In animal sacrifices the offal was removed and burnt outside the camp

Exodus 29:14 See also Leviticus 4:11–12, Leviticus 8:17, Leviticus 16:27; Numbers 19:3–5, Numbers 19:5

But burn the flesh of the bull and its hide and dung outside the camp; it is a sin offering.

Jesus Christ bears the believer's disgrace

Hebrews 13:11–13
