The Jews have been subjected, susceptible and affected and judged by all of God's assessment and judgments. They are not treated any different than the Gentiles.
They were chosen for this purpose. God When The Jews turned their back on God and disobeyed Him - they were judged and God lifted His hand of protection and their enemies were able to harm them.
They were not just chosen because they are Jews - They were chosen to be the ones who God would bring many prophets and to also bring His word - ( The Bible )
because they lived lives in obedience to God. They chose to live a consecrated and holy lifestyle and to obey God. This is the way that God chose the Jewish race.
Deu 7:6 Because thou art an holy people unto the LORD thy God: the LORD thy God hath chosen thee to be a special people unto himself, above all people that are upon the face of the earth.
Deu 14:2 Because thou art a holy people unto the LORD thy God, and the LORD hath chosen thee to be a peculiar people unto himself, above all the nations that are upon the earth.
This word " BECAUSE " - " BECAUSE " thou are a holy people is used in the Bible - 1231 times total to mean " BECAUSE ".
They were chosen under the conditions and " BECAUSE " they were really a holy people.
God has throughout all of the time in history since the beginning - also called the " GENTILES " to serve Him and to obey His law and ordinances.
Gentiles were never excluded as a group from salvation and denied the opportunity to live righteous lives in honor, respect, and obedience to God and His laws. We know that there were Gentiles in various places throughout the Old Testament who were Godly and just characters. Such as various gentile kings and even gentiles who assisted the Jews and spoke of living for God and doing the right thing.
The Egyptians were given full opportunity to obey and know God.
Balaam was believed to be a gentile prophet but He eventually turned against the god of Israel
Caleb also in Num 32:12 Caleb the son of Jephunneh the Kenezite had wholly completely followed the LORD. The great hero of Judah was a Kenizzite, one of the Canaanite tribes (Gen 15:19)

Also here in Jos 9:7 And the men of Israel said unto the Hivites, Peradventure ye dwell among us; and how shall we make a league with you?
Jos 8 And they said unto Joshua, We are thy servants. And Joshua said unto them, Who are ye? and from whence come ye?
Jos9 And they said unto him, From a very far country thy servants are come because of the name of the LORD thy God: for we have heard the fame of him, and all that he did in Egypt,
Also Othniel (Judg 3:9): Othniel was Caleb’s brother and also a Canaanite - - Jdg 3:9 And when the children of Israel cried unto the LORD, the LORD raised up a deliverer to the children of Israel, who delivered them, even Othniel the son of Kenaz, Caleb's younger brother.

ALSO - The Gentile People of Nineveh in Jonah 3........ The gentile people of Nineveh believed in God at the preaching of Jonah.
Not many Gentiles were mentioned and detailed in description and recorded as serving and believing in God, however, the option was there and there were gentiles who did serve God in the Old Testament. Also, there were many Gentiles around other various parts of the world who were Godly people - though the Bible does not record their location.
The Gentiles had full opportunity to serve God and to obey Him - However, The Hebrew people were chosen by God with the obligation, task, duty, and responsibility of obeying and preserving His word and living clean, holy and Godly lives. Noah was not a Hebrew / Jew - and He preached to everyone around Him.
The Bible describes Him as a preacher. We see in the Old Testament that God is giving Gentiles a chance to live for Him and all people to do right and obey.
The Jews have been through horrible and terrible trials because God lifted His hand of protection from them - just like he promised to do - if they continually continued to disobey Him. God kept His word and The Jews were scattered and persecuted and tormented by the evil people of the world until God returned them back to their homeland and began to protect them once again - we see all of this in the proof - in historical fact. Just as God promised and prophiced all of this.
