Hosea 13 and 14 conclude the prophecy with a plea from God to His people. God reminds them that He is the only true God they have known. The others will not, cannot save them from what is going to happen to them. God makes a final plea that they turn back to God, admit their failures and receive His healing.
Revelation 4 begins with an open door. The writer is invited into the throne room of God. We see the four living creatures we have encountered in Ezekiel and Daniel there singing continuously to the Lord.
There are 24 elders who bow down and worship God because he is the Creator of all things. The elders represent the faithful from the Old Testament (12 tribes of Israel) and the New Testament (12 apostles). All the faithful are there from every time and place worshiping God.
