In this passage, we are reminded of the pivotal role Moses played as a mediator between God and the Israelites during their journey through the wilderness. The 'assembly' refers to the gathering of the Israelites, who were led by Moses after their exodus from Egypt. The angel mentioned is traditionally understood to be a divine messenger, signifying God's presence and communication with Moses on Mount Sinai. This encounter is crucial as it marks the moment when Moses received the 'living words'—the commandments and laws that were to guide the Israelites in their covenant relationship with God.
These 'living words' are not just historical artifacts but are described as 'living' because they continue to have relevance and power in the lives of believers. They are meant to be dynamic, guiding principles that shape moral and spiritual life. The verse underscores the importance of these teachings being passed down through generations, ensuring that the wisdom and guidance they offer remain alive and influential. It serves as a reminder of the enduring nature of God's word and its capacity to inspire and direct the faithful across time.
