I recently found out that there seems to have been the discovery (years ago) of the 'upper room' mentioned in Scriptures in regards to where Yahshua ate with his Apostles the evening before he was executed. I do not know how anyone knows the location because it was not given in Scriptures.... it's all guess work and probably a money making tourist attraction. This makes me think of Yahshua overturning the tables at the temple where folks had been selling oxen, sheep and doves alongside with the money changers. "Do not make the House of my Father a house of bartering".
In modern day Jerusalem folks shouldn't pick any old place and give it a 'holy' name, then include the place with tour guides.
There is more than one mention of an 'upper room' in Scriptures but the 2nd most famous one is where the Apostles gathered.
It is not so much where these rooms were located but what's important is the events that occurred in them. Folks have glazed over the lesson in order to adore the physical things.
Quote from Israel Advantage Tours: This structure has been regarded as the traditional site of the Last Supper since the fourth century AD.
According to scripture, the Upper Room is where the Last Supper took place and where Jesus washed His disciples’ feet (John 13:1–20). It is where the disciples gathered in fear after the death of Jesus. Jesus appeared in this room on two occasions after the Resurrection. It is here He showed Thomas the wounds in His body. It is where the 120 believers prayed on the Day of Pentecost. The Bible tells us that tongues of fire appeared to them and they were all filled with the Holy Spirit and began to speak in other languages (Acts 2:1-4). At this place the church of Jesus Christ was born.
No where in Scripture is the location of the 'upper room' where the passover meal was eaten ever revealed. Yahshua's instructions for his disciples to make preparations for this meal are found recorded here, which I have lightly paraphrased. Please read from your bible when you have time:
