Adam Clarke on Isaiah 32:7

The instruments also of the churl are evil "As for the niggard, his instruments are evil" - His machinations, his designs. The paronomasia, which the prophet frequently deals in, suggested this expression וכלי כליו vechelai kelaiv. The first word is expressed with some variety in the MSS. Seven MSS. read וכילי vekili, one וכל vechol, another וכולי vecoli.

To destroy the poor with lying words "To defeat the assertions of the poor in judgment" - A word seems to have been lost here, and two others to have suffered a small alteration, which has made the sentence very obscure. The Septuagint have happily retained the rendering of the lost word, and restored the sentence in all its parts: Και διασκεδασαι λογους ταπεινων εν κρισει· ולהפר דברי אביון במשפט ulehapher dibrey ebyon bemishpat, "And disperse the words of the poor in judgment. "They frequently render the verb הפר haphar by διασκεδασαι, A MS. reads ולדבר uledabber, which gives authority for the preposition ל lamed, to, necessary to the sense, and the Septuagint, Syriac, and Chaldee read במשפט bemishpat, In judgment.
