Hebrews 4:1-10 deals with the Sabbath-rest for the People of God. The Jews in the wilderness could not enter because of disobedience, but we, thanks to Jesus, who believe can enter. Remember, “Today” is the key word. Read it carefully!
Ezekiel 20. Though Israel pleaded with God, He would not listen because of their rebellious idol worship. God through Ezekiel then retold the history of Israel and their idolatry and blasphemy, Israel will be severely punished, but in the end, God will restore Israel. The chapter ends with a prophecy against the South, God will destroy the Southern forests.
Psalm 102. A penitential psalm. It recalls the great deeds and miracles God did for His people in the wilderness, and how they disobeyed and turned to idols, even to the point of child sacrifice. In spite of this God is still merciful and there is still hope. It ends with a Hallelujah!
