Shiv'a Veshiv'im Umatayim - mi yodeya?

Question

Who knows two hundred seventy-seven?

?שבעה ושבעים ומאתים - מי יודע

In the spirit of the song "Echad - mi yodeya", please post interesting and significant Jewish facts about the number 277.

I see no need to seed this particular entry with a lazy gematria.

Check out mi-yodeya-series for the previous two hundred seventy-six entries in this ongoing series.

Answer 1

According to Rebbi in Sanhedrin 17b-18a, a town must have a minimum of 277 residents in order to be fit for the formation of a Sanhedrin court. See Rashi there (top of 18a) for the details about how this number is derived.
