During Jesus ministry of 3 1/2 years on the earth, he repeatedly quoted from the Hebrew Scriptures (commonly but inaccurately called "the Old Testament") to show what is right and what is wrong, what is prophetic, explaining this to his disciples, giving deep insight into the "Kingdom".(see Matt 13 where Jesus gave a series of seven different illustrations regarding the Kingdom)
In contrast, the Jewish religious leaders not once used the Hebrew Scriptures, but just told the common Jews what to believe but which were mostly lies, in which Jesus said in his scathing denunciation to them: "Woe to you, scribes and Pharisees, hypocrites ! because you shut up the Kingdom of the heavens before men; for you yourselves do not go in, neither do you permit those on their way in to go in. Woe to you, scribes and Pharisees, hypocrites ! because you travel over sea and dry land to make one proselyte, and when he becomes one, you make him a subject for Ge·henʹna (or everlasting destruction) twice as much so as yourselves (by filling their minds and hearts with falsehoods, so that these are moved to keep imparting the same lies and even put to death [see John 16:2, 3] those who ' instruct others in the way of Jehovah ', Ps 27:11)."(Matt 23:13, 15)
After "raking" the Jewish religious leaders "over the coals" for telling lies (see Matt 16:6, 12), who wanted to hinder or stop anyone from expressing the truth about Jehovah God, Jesus now says to them: "Serpents, offspring of vipers, how will you flee from the judgment of Ge·henʹna ?(or everlasting destruction, not "the damnation of hell" as in the KJV) For this reason, I am sending to you prophets and wise men and public instructors. Some of them you will kill and execute on stakes, and some of them you will scourge in your synagogues and persecute from city to city, so that there may come upon you all the righteous blood spilled on earth, from the blood of righteous Abel to the blood of Zech·a·riʹah son of Bar·a·chiʹah, whom you murdered between the sanctuary and the altar."(Matt 23:33-35)
Corrupted Judaism taught "hellfire" and the "immortality of the soul", for 1st century Jewish historian Josephus (37 ?-101 C.E.?) wrote: "They believe that souls have power to survive death and that there are rewards and punishments under the earth for those who have led lives of virtue or vice: eternal imprisonment is the lot of evil souls, while the good souls receive an easy passage to a new life.” (Jewish Antiquities, XVIII, 14 [i, 3]) “Every soul, they maintain, is imperishable, but the soul of the good alone passes into another body, while the souls of the wicked suffer eternal punishment.” (The Jewish War, II, 162, 163 (viii, 14)
So, because the Jewish religious system was incorrigible, was "beyond healing" (2 Chron 36:16; "no remedy", KJV), Jesus now said: "Jerusalem, Jerusalem (as the Jewish religious center for telling falsehoods and trampling down "the truth"), the killer of the prophets and stoner of those sent to her—how often I wanted to gather your children together the way a hen gathers her chicks under her wings ! But you did not want it. Look ! Your house (or the temple in Jerusalem, see 1 Kings 9:7-9) is abandoned to you. For I say to you, you will by no means see me from now until you say (quoting from Ps 118:26), ‘Blessed is the one who comes in Jehovah’s name !’” (Matt 23:37-39)
The Trinity, hellfire or hell, the immortality of the soul, are just a few of the religious falsehoods that continue to be promoted by so-called "Christianity", but just as with the Jewish religious system with its "glorious temple" that saw its end in 70 C.E. at the hands of the Roman armies (see Luke 19:41-44; 21:5, 6), so likewise of so-called "Christianity" that will see its end in the near future at the hands of political elements (Rev 17:16, 17), it being a major part of the false religious empire called Babylon the Great.(Rev 17:5)
