Israel were the ones married to God. They were the ones who rejected Christ. It's not hard t figure out who the beast was, especially since The Jews were called beast in Ecclesiastes 3:16-19 ,Titus 1:10-16, Jude 1-19, and 2nd Peter chapter 2,Titus 1:10-16- 10 Jude 1-19- 1 ,2nd Peter chapter 2 2. Who were the antichrists?
1 John 2:18
18Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time. 19They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us
This scripture is talking about the people who had gotten saved and then stepped out of the church back into law and those were the antichrists. Rev 13:2-4 And the beast which I saw was like a leopard, and his feet were like those of a bear, and his mouth like the mouth of a lion (Below I have an article explaining what this symbolizes. I will say this, the Lords people was Israel and the Lord compared Himself to a lion, leopard, and a bear robbed of its cubs ( Hos 13:7-8), while likening His restored people to a lion’s cubs, birds, and doves (Hos 11:10-11).) And the dragon (Satan) gave him his power and his throne and great authority. 3 One of the heads of the beast seemed to have had a fatal wound, but the fatal wound had been healed. The whole world was filled with wonder and followed the beast. 4they worshiped the dragon (Satan) because he gave his authority to the beast; (Israel) and they worshiped the beast, saying, "Who is like the beast,and who is able to wage war with him?"
Rev 13:5-6 The beast was given a mouth to utter proud words and blasphemies and to exercise its authority for forty-two months (3 ½ yrs the trib was from 66 ½ to 70 A.D exactly 3 ½ yrs. The first 3 ½ years was the 1st h half of Dan. 70th week, when Jesus preached the new covenant message until he was cut off in the mist of the week). 6 It opened its mouth to blaspheme God, and to slander his name and his dwelling place and those who live in heaven. Rev 10- “If anyone is to go into captivity, into captivity they will go. If anyone is to be killed[c] with the sword, with the sword they will be killed.” In 12 whose fatal wound had been healed In 14- It ordered them to set up an image in honor of the beast who was wounded by the sword and yet lived.
Jer 30:12-18, 22-24 GOD SPEAKING TO ISRAEL JEREMIAH
12 For thus saith the Lord, Thy bruise is incurable, and thy wound is grievous.13 There is none to plead thy cause, that thou mayest be bound up: thou hast no healing medicines.14 All thy lovers have forgotten thee; they seek thee not; for I have wounded thee with the wound of an enemy,
