The answer is: In a dream

Matt 2:13 - The angel only appeared to Joseph in a dream and didn't actually visit them in a physical sense. Also the angel appeared only to Joseph and not to them both.

Isn't it fascinating how dreams can play such a pivotal role in shaping the course of history? In the case of Jesus' family, an angel appeared to Joseph in a dream, providing him crucial guidance at a time of danger. This wasn’t an isolated occurrence either; throughout the Bible, dreams often serve as a divine communication line. For example, Jacob's ladder in Genesis and Pharaoh’s dreams interpreted by Joseph just highlight how God communicates in mysterious ways, so it's interesting to see this theme continue with Joseph the carpenter.

The angel's warning came mid-flight from the fruitful town of Bethlehem to Egypt, a place steeped in history and symbolism. Ancient Egypt was not only a geographical refuge but also resonated deeply as a historical site representing bondage and liberation for the Israelites. Here, then, we see a deeper layer: Jesus, like Moses before him, finds sanctuary in Egypt, deepening the connection between the two figures destined to lead their people.

Interesting fact: Egypt's culture reverberates even in art, where biblical narratives are often depicted using symbols mixing ancient Egyptian motifs. Thus, you witness biblical ties transcending mere stories, weaving the old and new in a tapestry designed for redemption! Ultimately, the dream served as divine protection, inviting every believer to recognize that communication can unfold in various, sometimes unexpected, ways.
