Could Knave be related to ....

Ganav גַנָב related here by writer David Curwin to gambit by way of the Arabic janab [janibu]

Gonnif גנב , ‘Thief’ is found in Yiddish, Judeo-Italian and Judeo-Spanish per linguist and educator Asya Pereltsvaig at Languages of the World (p.252, edition 2012)

However, knave here relates to a Germanic word for boy . The g and j can alternate in Arabic , but g and kh don't in either Hebrew or Arabic. The kh guttural is apparently the sound behind the kn phonogram as indicated here. These whimsical word lists might do better if they were sound-based, rather than spelling-based. The words share status as epithets with similar meaning, but that should not fuel a goose-chase through historical phonological processes in search of just the right combination to create a shared origin.
