Dough

Dough in the ancient world was typically made from wheat or barley flour mixed with water, then leavened with a piece of fermented dough retained from a previous batch. The unleavened dough (maṣṣôt) that the Israelites carried out of Egypt in kneading troughs on their shoulders—without time for leavening—became the basis for the annual Feast of Unleavened Bread and the instruction to eat no leavened bread during the seven days of Passover (Exod. 12:34, 39). The absence of leaven in the Passover dough thus memorialized the urgency of the Exodus.

Hosea 7:8 uses the image of Ephraim as "a cake not turned"—half-raw dough on one side—as a vivid metaphor for a nation only half-committed in its allegiances and compromised by mixing with the nations. Numbers 15:17–21 required that the first portion of kneaded dough be presented to the LORD as a contribution, a principle Paul applies theologically in Romans 11:16: "If the dough offered as firstfruits is holy, so is the whole lump."
