Radak, Malbim: It is Yerushalayim. She must widen it due to the many children who will come.
What are the curtains of her dwelling?
Radak: The other cities of Yisrael.
Malbim: The other cities of Yehudah. People dwell in the big tent. If guests come, they add small dwellings. These are the curtains of the additions.
Where should the curtains lean?
Rashi: To a far place. Radak - it says "b'Eretz Chadrach v'Damesek Menuchaso
Why does it say "Al Tachsochi"?
Malbim: Do not refrain for a moment from constantly spreading and untying [the curtains], for the new children coming will constantly increase residents, and new dwellings must be added.
What are "Meisarayich"?
Rashi: They are the thin ropes that hang at the bottom of tents and they tie them with pegs and insert them in the ground.
Why should the ropes be lengthened and the pegs strengthened?
Malbim: They should be prepared to untie the tent constantly, when they need to extend it. It will not stand in its border for a moment. The pegs should be prepared to supports other tents. This is a metaphor for the increase and spread of the nation.
