'Leavened' in the Bible

You shall not eat {with it} anything leavened; seven days you shall eat {with it} unleavened bread of affliction, because in haste you went out from the land of Egypt, so that you will remember the day of your going out from the land of Egypt all the days of your life.

All of them commit adultery, like a burning oven whose baker has stopped from stirring the fire, and from kneading [the] dough until it is leavened.
