Why do you keep going on about Paul of Tarsus to me? I’ve already told you I don’t put credence into his work.The "Christian" bible also contains the Law and the prophets. Does that mean you have to reject the law and the prophets too? Apparently the "LORD" has problems with the "sons of Israel" as well. It seems he found no faithfulness or kindness among them, nor knowledge of God in the Land (Hosea 4:1). For this reason they have been under judgment, both Ephraim and Judah (Hosea 5), and will remain so until they acknowledge their guilt. Ephraim and Judah will not be revived until after "two days" (Hosea 6:2), which would be 2000 years. Per Zechariah 12, Judah has now been coming into the land of Jacob, but they have not acknowledged the prophet to come of Dt 18, and wept for their act of piercing "Me". (Zechariah 12:10). The "new covenant"/new testament is a sham of Paul and his apparent associates, but Paul's church is the woman bought with the equivalent of 30 shekels of silver to help the sons of Israel seek the LORD in the "last days". (Hosea 3)
Now about the “Old Testament. Actually there are key differences between the Jewish Scriptures (the TaNaKh) and the Christian “Old Testament”. But you probably don’t know that nor what those differences even are. When non-Jews try to tell Jews what their own Scriptures “really” mean is extremely arrogant and insulting. The Jews don’t need others to tell us what our own Scriptures mean. We’ve been studying and following them since long before Jesus of Nazareth was born and the Christian “New Testament” was written. It is quite clear from what you have written above that you don’t understand the TaNaKh.
