Is there something in the bible about the gentiles not knowing any better and are innocent, but if a jew does the same thing he is guilty because he knows better, is this from the bible or? help me
The closest thing that comes to my mind is:
47 And that servant who knew his master’s will, but did not make ready or act according to his will, shall receive a severe beating. 48 But he who did not know, and did what deserved a beating, shall receive a light beating. Every one to whom much is given, of him will much be required; and of him to whom men commit much they will demand the more. (Luke 12:47-48)
However, the ignorant servant is not considered innocent but deserving of a lighter punishment. Though the Gentiles did not receive the Law of Moses, they, like all men, still had the Natural Law written in their hearts.
Wisdom 13:1-19 Nature worship, idolatry, and the carpenter and his wooden idols
1 From studying the works, foolish men did not discern the artist. If the beauty of these works made humans think their Gods, then let them know how far more excellent is the artist itself.
3 If these mighty works impressed them to the point where they consider these works Gods, then how much more powerful is the artist itself?
6-9 But the blame of these peoples are less, for even when they have gone astray, they actively search for God, tirelessly interpreting his works, but are constantly distracted by what they see. Yet, even these persons are not pardoned. They grew in knowledge, speculating the world: How couldn’t they find God more quickly?
10 The greater blame is incurred on those who considered things made by human hands to be Gods: silver, art, and statues of beasts, things that no longer exist today.
:hmmm: The above passage hints that a person who truly wishes to find God will be somewhat pardoned, but the person in question must communicate with God in order to actually benefit from the wisdom which he or she has gained. Albert Einstein is a classic example of this: people who recognize the ingenuity of the works, search for God, yet haven’t found him.
During the times of the Old Testament, even though the Gentiles were not connected with God via covenant, they could have still entered Heaven via benevolence. Biblical history has shown that there were godly gentiles and benevolent pagans: People who weren’t entrenched into dumbness, they recognized the God of the universe when he came in the form of his people: Israel.
The Gideonites were a mighty people with royal cities, and they were not arrogant. Even though they allied themselves with Israel via means of deception, they made the right choice in many ways. Their relationship with Israel was approved by God, who protected them and even allowed them to take revenge on Saul and his family.
Jesus Christ and his loyal apostles defended the gentile’s dignity multiple times throughout the New Testament, emphasizing the goodness of the new covenant.
To whom much is given, much has been expected.
You may be thinking of Romans 2
 Tribulation and anguish upon every soul of man that worketh evil, of the Jew first, and also of the Greek.  But glory, and honour, and peace to every one that worketh good, to the Jew first, and also to the Greek.
But this must be understood in context. He goes on to say:
 For there is no respect of persons with God.  For whosoever have sinned without the law, shall perish without the law; and whosoever have sinned in the law, shall be judged by the law.  For not the hearers of the law are just before God, but the doers of the law shall be justified. . . .
So it wasn’t so much being Jewish or Gentile; it was more a matter of having knowledge and not acting on it (which in that context applied in a special way to the Jewish religious leaders). But as I see it the admonition does not apply to modern Jews. Those who “know better” are now Catholics, who have Christ and the fullness of grace and truth, and will be judged if we do not respond to it.
