The pronoun They refers to the people of Israel present at the time. In some languages it may be appropriate to make this clearer in translation, as in Good News Translation.

Defrauded … oppressed: see verse 3.

Taken anything from any man’s hand: in light of verse 3, the sense is “you have not taken a bribe from anyone” (Parola Del Signore: La Bibbia in Lingua Corrente). Since a literal translation may be misleading, the model of Parola Del Signore: La Bibbia in Lingua Corrente may be helpful in many languages. Others may prefer to follow New Century Version, which reads “taken anything unfairly from anyone.”
