170 was the number of years of actual slave labor performed by the Jews in ancient Egypt. - Torat haMinchah, 19th sermon, page 161

According to what I can see of Google's copy of Artscroll's translation of צאינה וראינה, there are 170 times in the Torah where Hashem's name appears before Moshe's. However, according to my very limited ability to read the original Yiddish, there are 175. So I don't know.

When Jerusalem was conquered by the Crusaders in 1099, the Jewish residents were annihilated. The last remaining Jews, battling the invaders, found refuge in a synagogue. When the conquest was complete, the Crusaders set the synagogue alight, burning everyone inside alive. By the time the RAMBAN arrived, Jewish Jerusalem had been demolished and in ruin for 170 years, and few Jews remained in the city. The continuum of Jewish life in the city was rejuvenated with the RAMBAN’s arrival.
