First of all, when God created the Sabbath, blessed the seventh day and sanctified it, there were no Jews to be found on the face of the planet earth. Man was created already of course, but the races had not been established, and were not for quite some years. The Sabbath was made for man, not Jews.
Second, just because you didn't see the commandments written until Moses, that doesn't mean that they didn't exist prior to that. Sin is transgression of the law. Without the law, there is no sin. But we see sin spoken of in Genesis 4, then we see Cain sin. So the commandments existed right from man's beginning, and again, there were no Jews yet. The commandments were made for man, not Jews.
By the way.. I see you went back and forth with the word Israelites and the word Jews, but these words are not interchangeable... There was the kingdom of Israel and the kingdom of Judah (the Jews)... two different peoples.
Some proof that the 10 commandments were intended for the rest of the world..........
Psalm 22.27 All the ends of the world Shall remember and turn to the LORD, And all the families of the nations Shall worship before You. 28 For the kingdom is the LORDs, And He rules over the nations... (Judah and Israel are not specified,, ALL families)
Zech 14.17 (Speaking of the time of Christ's return) And it shall be that whichever of the families of the earth do not come up to Jerusalem to worship the King, the LORD of hosts, on them there will be no rain. 18 If the family of Egypt will not come up and enter in, they shall have no rain; they shall receive the plague with which the LORD strikes the nations who do not come up to keep the Feast of Tabernacles. 19 This shall be the punishment of Egypt and the punishment of all the nations that do not come up to keep the Feast of Tabernacles. (Judah and Israel are not specified,, all nations shall come and worship,, keeping the Feast of Tabernacles which is an annual Sabbath, which makes it part of the 4th commandment. If they do not, they will be punished, whomever they are.)
Micah 4.1 (Speaking of the time of Christ's return) Now it shall come to pass in the latter days That the mountain of the LORDs house Shall be established on the top of the mountains, And shall be exalted above the hills; And peoples shall flow to it. 2 Many nations shall come and say, Come, and let us go up to the mountain of the LORD, To the house of the God of Jacob; He will teach us His ways, And we shall walk in His paths. For out of Zion the law shall go forth, And the word of the LORD from Jerusalem. 3 He shall judge between many peoples,,,
Isaiah 66. (Speaking of the time of Christ's return) 23 And it shall come to pass That from one New Moon to another, And from one Sabbath to another, All flesh shall come to worship before Me, says the LORD. 24 And they shall go forth and look Upon the corpses of the men Who have transgressed against Me. (Yes, the Sabbath will still be a part of God's great plan, because God does not change!)
Isaiah 56. (Salvation for the Gentiles) 1 Thus says the LORD: Keep justice, and do righteousness, For My salvation is about to come, And My righteousness to be revealed. 2 Blessed is the man who does this, And the son of man who lays hold on it; Who keeps from defiling the Sabbath, And keeps his hand from doing any evil. 3 Do not let the son of the foreigner Who has joined himself to the LORD Speak, saying, The LORD has utterly separated me from His people; Nor let the eunuch say, Here I am, a dry tree. 4 For thus says the LORD: To the eunuchs who keep My Sabbaths, And choose what pleases Me, And hold fast My covenant, 5 Even to them I will give in My house And within My walls a place and a name Better than that of sons and daughters; I will give them an everlasting name That shall not be cut off. 6 Also the sons of the foreigner Who join themselves to the LORD, to serve Him, And to love the name of the LORD, to be His servants Everyone who keeps from defiling the Sabbath, And holds fast My covenant 7 Even them I will bring to My holy mountain, And make them joyful in My house of prayer... (The Sabbath and the commandments were meant to be a identifier of God's people. So all people will eventually get the chose to be a part of the covenant, and if the so choose, that will be known by their actions, because this is how we show our love of God, by keeping his commandments. 1 John 5.2)
