Luke 21: 24: And they shall fall by the edge of the sword, and shall be led away captive into all nations: and Jerusalem shall be trodden down of the Gentiles, until the times of the Gentiles be fulfilled.
“Jerusalem shall be trodden down of the Gentiles” is in Hebrew, “Yerushalem Tel”.
“Yerushalem Tel” has a gematria of 3830 (it is the sum total of the numerical value for each Hebrew letter that forms the phrase).
1948 (modern Israel became a nation) was the Jewish year 5708.
5708 – 1878 = 3830 or A.D. 70.
1878 is the number we subtract till we come to A.D. 70 (the Jewish year 3830). In A.D. 70 the Romans sacked Jerusalem.
