The answer is: Three

Matt 13:33

In the Gospel of Matthew, Jesus shares a colorful parable about the leaven that has sparked curiosity and discussion across time. When the woman in the story hides three measures of flour in leaven, it’s not just a random number; it carries significance. Interestingly, three measures of flour roughly equal about 50 pounds! That's enough to bake bread for a small crowd or even a village feast. This vast quantity highlights the abundance and transformative power of the leaven—symbolizing how a small act or idea can create a considerable impact.

Moreover, this concept echoes throughout scripture—think of the mustard seed parable earlier in the chapter, where the tiniest seed grows into a large tree. Both parables urge us to recognize the potential of small beginnings. They remind us that change—whether personal or societal—often starts in the smallest places and can expand beyond our imaginations.

It's also worth noting that leaven is often used in a dual light throughout the Bible. While it signifies holiness in some contexts—like at festivals celebrating obedience—it can also symbolize corruption in others (think of the Pharisees). Thus, the message isn't one-dimensional. Instead, it invites contemplation on what "leaven" we choose to embrace in our lives. When the yeast of good deeds or thoughts is tucked away in the texture of our daily grind, it has the power to rise and fill the entire loaf, serving not just us, but all those around us.
