The Meaning of the Number 70
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 judgment.
Seventy is also specially connected with Jerusalem. The city kept 70 years of Sabbaths while Judah was in Babylonian captivity (Jeremiah 25:11). Seventy sevens (490 years) were determined upon Jerusalem for it to complete its transgressions, to make an end for sins and for everlasting righteousness to enter into it (Daniel 9:24).
The Bible records Jesus Christ giving at least 70 parables during His ministry.
