Editing Melacha of Tying (section)

== The Halacha ==
The Alter Rebbe rules in Shulchan Aruch siman 317: Tying and untying are among the Avos Melachos, as in the Mishkan the chilazon trappers would tie and untie their nets, since all nets are made of knots, and they are permanent knots. Sometimes they needed to take threads from one net to add to another, untying here and tying there.

From the Torah one is only liable for a permanent knot meant to remain forever, meaning he ties it intending it to remain as long as possible and as long as he doesn't need to untie it. Even though he may need to untie it soon and will untie it, since when tying it he doesn't set a specific time to untie it, and it could remain forever, this is called a permanent knot and one is liable for tying and untying it. But if he sets in his mind any specific time that he will definitely untie it, even if it's a very long time, this is not considered permanent from the Torah and he is exempt for both tying and untying it. However, the Rabbis also consider this permanent since it remains for some time, and it is forbidden both to tie and untie it.
