Seventy has a sacred meaning in the Bible that is made up of the factors of two perfect numbers, seven (representing perfection) and ten (representing completeness and God’s law). As such, it symbolizes perfect spiritual order carried out with all power. It can also represent a period of judgement.
Malkie Janowski, at Chabad, continues:
When disunity came to the world, it took the form of seventy. When we see a true example of togetherness in the Bible, it takes the form of seventy. It’s a number tha[t] can be pulled either way, all depending on you.
Seventy is two sides of the same coin representing unity and disunity — “all the offspring of Jacob, seventy soul”, travelled to Egypt in spiritual and physical unison, but by way of contrast after the Tower of Babel Elohym scattered the people and divided them to form seventy nations.
24 Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy. 25 Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks: the street shall be built again, and the wall, even in troublous times. 26 And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined. 27 And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate.
The Church Age ends at the beginning of the pre-Tribulation Rapture, sitting at midpoint of Daniel’s 70th Week:
