Hebrews are a people, a race. Jews are a religion.
Hebrews consist of all the descendants of Abraham, Jews consist of those who worshiped the serpent in the wilderness, thus was born the saying "salvation is of the Jews"
Read John 4:20-22 Jesus is speaking of the mountain and the temple when He says " ye worship ye know not what ", for the descendants of Jacob (Israel) the Jews, worshiped the devil, because Moses told them it was God. Moses made an image and gave the image a voice and those who would not look upon the image died.
Read; And Moses prayed for the people. And the LORD said unto Moses, Make thee a fiery serpent, and set it upon a pole: and it shall come to pass, that every one that is bitten, when he looketh upon it, shall live. And Moses made a serpent of brass, and put it upon a pole, and it came to pass, that if a serpent had bitten any man, when he beheld the serpent of brass, he lived. Num 21:7-9 (KJV)
Now read Revelation 13:11-18;
And I beheld another beast coming up out of the earth; and he had two horns like a lamb, and he spake as a dragon. And he exerciseth all the power of the first beast before him, and causeth the earth and them which dwell therein to worship the first beast, whose deadly wound was healed. And he doeth great wonders, so that he maketh fire come down from heaven on the earth in the sight of men, And deceiveth them that dwell on the earth by the means of those miracles which he had power to do in the sight of the beast; saying to them that dwell on the earth, that they should make an image to the beast, which had the wound by a sword, and did live. And he had power to give life unto the image of the beast, that the image of the beast should both speak, and cause that as many as would not worship the image of the beast should be killed. And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads: And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name. Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six.
They are the same story, Revelation 13 has already happened, it is speaking of Moses. The number six hundred threescore and six is referring to Solomon's temple that he build to hornor the false God of Moses.
Read 1Kings 10:14
I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan.
Rev 2:9 (KJV)
