You're just doubling down on your mistakes now. Yes: lawfully means legally. No international or humanitarian law prevents the citizens of a land from using armed resistance against an occupying force. That's why you can't show me the law that prohibits it: that law does not exist.

Laws aren't written to describe the myriad things which are permitted. They're only written to prohibit or restrict the things which aren't.

Some Israelis want to believe that Palestinians aren't lawfully justified in using armed resistance against the Israeli occupation. But that of course is false. Just as Jews were able to use armed resistance in creating Israel, Palestinians are justified in using armed resistance today. The only legal restrictions the Palestinians face when using armed resistance against the Israeli occupation is that they may not violate the laws of war, ie, the Geneva Conventions et al... even though Jewish groups violated those laws prior to 1948.
