Prepared Grain Offerings from Oven, Griddle, or Pan
The forward Bible connection is not hidden in how a cake is broken. Scripture itself returns to this offering in Leviticus 6 and later uses priestly altar provision as part of Paul's argument in 1 Corinthians 9.
Where this fits in the story: Exodus 29 provides the sanctuary system in which grain/oil accompany offerings.
Where Scripture takes it next: 1 Corinthians 9:13–14 provides broad inspired reasoning from altar-worker provision.
Evidence boundary: breaking cakes → Last Supper: no warranted canonical Thread.
