The city is home to other eruvs — a large one in Manhattan was extended this year from Midtown to Houston Street — and many are in predominantly Jewish areas. […] “We live in a day and age,” he continued, “where if you don’t have an eruv, you’re taking yourself off of many people’s lists.”"; "‘Fat’ is the word you hear shouted in the playground, or on the street – it's never allowed over the threshold of the house. My mum won't have that filth in her house. At home, together, we are safe. It's like an eruv for the slow and soft."Jewish
