The answer is: Three

Matt 13:33

In this parable from Matthew, the choice of "three measures of flour" is not just a random detail; it carries rich symbolism and insight into the message of growth and transformation. To put it in a culinary context, three measures translates to about a bushel, which was enough to feed a small village in ancient times. This signifies that the effects of the leaven, representing the Kingdom of Heaven, are significant and expansive—far beyond just individual transformation.

In biblical history, leaven has denoted both life and corruption, depending on the context. Here, amidst the depiction of God’s reign, leaven isn’t seen as something negative but rather as a powerful force of change. The Gospel writer Matthew emphasizes that even small acts of faith can result in something enormous.

Moreover, leaven is often associated with yeast, which demonstrates an organic process of rising—a wonderful illustration of spiritual growth! Paul echoes this sentiment in his letters, encouraging believers to be mindful of the “leaven” of their lives, suggesting healthy spiritual influences can uplift one’s whole being. Also, traditionally during Passover, leavened bread is set aside, symbolizing sin and worldly concerns, bringing a whole new level to this viewers' understanding: embracing the productive influence in their lives rather than casting it aside.

So, when you think about leaven negatively or feel small in your religious community lately, remember the transformation—large-scale goodness—is massively within reach!
