'Dough' in the Bible
So the people took their dough before the yeast was added, with their kneading troughs bound up in their clothing on their shoulders.
They baked cakes of bread without yeast using the dough they had brought from Egypt, for it was made without yeast -- because they were thrust out of Egypt and were not able to delay, they could not prepare food for themselves either.
So Tamar went to the house of Amnon her brother, who was lying down. She took the dough, kneaded it, made some cakes while he watched, and baked them.
Children are gathering firewood, fathers are building fires with it, and women are mixing dough to bake cakes to offer to the goddess they call the Queen of Heaven. They are also pouring out drink offerings to other gods. They seem to do all this just to trouble me.
The first of all the first fruits and all contributions of any kind will be for the priests; you will also give to the priest the first portion of your dough, so that a blessing may rest on your house.
They are all like bakers, they are like a smoldering oven; they are like a baker who does not stoke the fire until the kneaded dough is ready for baking.
He told them another parable: "The kingdom of heaven is like yeast that a woman took and mixed with three measures of flour until all the dough had risen."
It is like yeast that a woman took and mixed with three measures of flour until all the dough had risen."
If the first portion of the dough offered is holy, then the whole batch is holy, and if the root is holy, so too are the branches.
Your boasting is not good. Don't you know that a little yeast affects the whole batch of dough?
Clean out the old yeast so that you may be a new batch of dough -- you are, in fact, without yeast. For Christ, our Passover lamb, has been sacrificed.
