Then one of the elders [of the heavenly Sanhedrin] said to me, Stop weeping! See, the Lion of the tribe of Judah, the Root (Source) of David, has won (has overcome and conquered)! He can open the scroll and break its seven seals! [Gen. 49:9, 10; Isa. 11:1, 10; Rev. 22:16.] And there between the throne and the four living creatures (beings) and among the elders [of the heavenly Sanhedrin] I saw a Lamb standing, as though it had been slain, with seven horns and with seven eyes, which are the seven Spirits of God [the sevenfold Holy Spirit] Who have been sent [on duty far and wide] into all the earth. [Isa. 53:7; Zech. 3:8, 9; 4:10.] And when He had taken the scroll, the four living creatures and the twenty-four elders [of the heavenly Sanhedrin] prostrated themselves before the Lamb. Each was holding a harp (lute or guitar), and they had golden bowls full of incense (fragrant spices and gums for burning), which are the prayers of God’s people (the saints). And [now] they sing a new song, saying, You are worthy to take the scroll and to break the seals that are on it, for You were slain (sacrificed), and with Your blood You purchased men unto God from every tribe and language and people and nation. [Ps. 33:3.] Saying in a loud voice, Deserving is the Lamb, Who was sacrificed, to receive all the power and riches and wisdom and might and honor and majesty (glory, splendor) and blessing!     Revelation 5:5-6, 8-9, 12 AMPC

2 Then I saw what looked like a sea of glass mixed with fire. I also saw those who had won the victory over the beast and its image and over the one whose name is represented by a number. They were standing by the sea of glass, holding harps that God had given them 3 and singing the song of Moses, the servant of God, and the song of the Lamb:

“Lord God Almighty, how great and wonderful are your deeds!  King of the nations,[a] how right and true are your ways!  4 Who will not stand in awe of you, Lord?  Who will refuse to declare your greatness?  You alone are holy.  All the nations will come and worship you, because your just actions are seen by all.”  Revelations 15:2-4

…Worship God! For the substance (essence) of the truth revealed by Jesus is the spirit of all prophecy [the vital breath, the inspiration of all inspired preaching and interpretation of the divine will and purpose, including both mine and yours]. After that I saw heaven opened, and behold, a white horse [appeared]! The One Who was riding it is called Faithful (Trustworthy, Loyal, Incorruptible, Steady) and True, and He passes judgment and wages war in righteousness (holiness, justice, and uprightness). [Ezek. 1:1.] His eyes [blaze] like a flame of fire, and on His head are many kingly crowns (diadems); and He has a title (name) inscribed which He alone knows or can understand. [Dan. 10:6.] He is dressed in a robe dyed by dipping in blood, and the title by which He is called is The Word of God. And the troops of heaven, clothed in fine linen, dazzling and clean, followed Him on white horses. From His mouth goes forth a sharp sword with which He can smite (afflict, strike) the nations; and He will shepherd and control them with a staff (scepter, rod) of iron. He will tread the winepress of the fierceness of the wrath and indignation of God the All-Ruler (the Almighty, the Omnipotent). [Ps. 2:9.] And on His garment (robe) and on His thigh He has a name (title) inscribed, king of kings and Lord of Lords. [Deut. 10:17; Dan. 2:47.] Revelation 19:10-16 AMPC
