The answer is: He had gone to Bethlehem for a family gathering

1 Sam 20:5-6

David's life during these tumultuous times was full of tension and danger. After all, the New Moon feast was a significant event in Israelite culture, marked by informal family celebrations and religious observance. By fabricating a story about a family obligation in Bethlehem, David cleverly masked his true intentions and his precarious state of the king's watchful eye.

Interestingly, this moment illustrates not just David’s desperation but also the loyalty between him and Jonathan, which is strikingly commendable. Jonathan, Saul's own son, was willing to go against his father to ensure David's safety. Their bond is chillingly reminiscent of other friendship echoes throughout the scriptures, like the profound connection between Ruth and Naomi or even the deep camaraderie found among Jesus' disciples.

Bethlehem also carries profound significance in biblical history, notably as the birthplace of David and, many generations later, the birthplace of Jesus. It symbolizes hope and rebirth, timeless values often renewed in the narratives that tie these stories to Jewish and Christian beliefs alike. Despite it all, David knew exactly how to use the situation to his advantage, highlighting the cunning and resourcefulness necessary for survival amidst betrayal and treachery that he faced.

Every drop of David's story overflows with lessons and nuances, embedding complexities of human relationships and existential threats that linger on today's landscape even among striving communities and devoted relationships.
