The answer is: Three

Genesis 18:1-2 - Three angels visited Abraham near the oaks of Mamre, one of whom confirmed that Sarah would bear a son within the year.

When Abraham was sitting at the entrance of his tent on a hot day, three angels approached him, as noted in Genesis 18. Now, imagine that picturesque scene near the oaks of Mamre – a perfect setting for heavenly visitors! The cool shade of the trees must have made for an inviting stop, not only for these celestial beings but for the ancient travelers who would seek out shelter along their way.

Interestingly, one aspect of this encounter to ponder is the symbolic meaning behind the number three. In many traditions, three is seen as a number of completeness or divine significance, echoing throughout the Bible. Think of the three gifts brought by the wise men during the nativity story, or Peter’s three denials of Jesus before redemption occurred!

And let's not overlook the wonderful moment when Sarah overheard the promise of a son only to laugh in disbelief. This scene is fascinating—it highlights human doubt in the face of divine proclamation. Yet, this tension is comforting in its familiarity; even today, we often wrestle with life's impossibilities.

Fun fact: the oaks of Mamre, where this event occurred, are still steeped in history. They mark a significant geographic and spiritual crossroads in ancient times, reminding us of the broader narrative of faith and the unexpected turns it can take. These themes of welcome, promises, and divine surprises resonate throughout the biblical texts, showcasing the beauty of unforeseen hope unfolding in our lives.
