Moses' time is short, but his message is crucial. He gathers all of Israel for one last, powerful address.
The phrase 'went and spake' here isn't just about starting a new speech, but continuing the important work. Moses is on the brink of death, his life's work about to conclude. Yet, he uses his remaining strength to 'go' to the people and speak God's words directly to them. This emphasizes the weight and authority of his message. It wasn't delivered in a casual note or a brief announcement; he went to them, ensuring they heard these vital, challenging words from his own lips. This direct delivery, as a final testament, carries immense gravity, ensuring the people couldn't later claim ignorance or misrepresentation. It's the ultimate act of a faithful shepherd ensuring his flock hears the truth, even as he prepares to depart.
