“…et ne quis supergrediatur neque circumveniat in negotio fratrem suum: quoniam vindex est Dominus de his omnibus…”
“...and that no man overreach, nor deceive his brother in business; because the Lord is the avenger of all these things…”
Ne/neque is no/nor.
The first qu word, translated as that, is a conjunction; the second qu word, translated as because, is a subordinating conjunction.
