“Behold, the days are coming … when I will fulfill the promise I made to the house of Israel and the house of Judah” (v14). Though it looked like Babylon would destroy Judah just like the Assyrians had destroyed northern Israel, God had a different plan. “I will cause a righteous Branch to spring up for David, and he shall execute justice and righteousness in the land. In those days Judah will be saved, and Jerusalem will dwell securely” (v15-16). The righteous Branch, the Messiah, would be priest and king “forever” (v18).
God’s faithfulness is like His covenant “with the day and the night” (v20). He doesn’t leave us, and He goes before us to plan for our salvation.
