144,000 is not a literal number, fren.
It is metaphorical. Just like 7 is the number of God (greater than the number of satan and man, 6), and 77 represents a perfection that reflects God…
So does 144,000 represent a derivative of 12 x 12 =144. The 144,000 represent the multitudes called from the 12 tribes (which includes both Messianic Jews and Gentiles). Short version, it's a multitude of multitudes.
