Understanding the Eruv in Manhattan

They strung up a fishing line, connected it between the city

structures until over half of Manhattan was

surrounded. A rabbi will drive around and inspect it before the

Sabbath, and if he spots a break, a special crew will fix it

before sundown on Friday. Because during this time,

observant Jews can't bring anything out the door of their

house, meaning they won't be able to carry their

wallets

outside or even bring their own babies outside.

But the wire acts as a closed boundary, turning that part of

Manhattan into one giant private area, making it

easier for Jews to do things while they technically

stay inside.
