What does the Bible say about the last words of God to Israel?

The last words given by God to the nation of Israel are found in Malachi 4:5-6, where He promises to send Elijah the prophet before the great and dreadful day of the Lord. This signifies the importance of prophetic revelation and God's continued commitment to communicate with His people, culminating in the embodiment of His Word in Jesus Christ. God’s prophets throughout the Old Testament played a vital role in pointing to Christ and preparing the way for His coming, emphasizing God's sovereignty and mercy in the redemption of His people.
