I also want to comprehend a nonTalmudic reason from Tanakh alone that proves Christ messiah was somehow not Yeshua.
well, here are four prophecies (with sources) that are the sine qua non of the future king messiah:
-He must build the ThirdTemple (Ezekiel 37:26-28)
-He must gather all the Jews back to the Land of Israel (Is. 43:5-6)
- He must usher in an era of world peace and bring an end to hatred,oppression, suffering and disease (Is. 2:4)
- He must spread the knowledge of the G-d of Israel, uniting the entire worldas one (Zechariah 14:9)
Jesus didn't fulfill these. Therefore, based on textual verses, he could not have been the promised future king messiah.
