Why do ye not understand my speech? even because ye cannot hear my word. Why do ye not understand my speech? - Την λαλιαν την εμην, This my mode of speaking - when illustrating spiritual by natural things: λαλια refers to the manner of speaking; λογος, to the matter or subject on which he spoke. For λαλιαν, the Codex Bezae had originally αληθειαν: why do ye not acknowledge this Truth of mine? A few other MSS. agree in this reading.
Because ye cannot hear my word - That is, ye cannot bear my doctrine: it comes too close to you; it searches your hearts, detects your hypocrisy, and exposes your iniquitous intentions and designs; and as ye are determined not to leave your sins, so ye are purposed not to hear my doctrine.
