He that hateth dissembleth with his lips,.... He that bears a grudge in his mind, and retains hatred in his heart against any person, hides it all he can, till he has an opportunity of showing it as he would; he pretends a great deal of friendship with his lips, that his hatred might not be known; he would be thought to be a friend, when he is really an enemy; he does not choose as yet to make himself known what he is.
Some render it to a sense the reverse, "the enemy", or "he that hateth, is known by his lips" ; so the Targum, Vulgate Latin, and Syriac versions: if you carefully watch him, mark his words, and observe what he says, you will find out the hatred that lies in his heart; he cannot forbear saying something, at one time or another, which betrays the malignity of his mind;and layeth up deceit within him; or, "though he layeth up", &c.
hides it as much as he can, yet it will show itself in some way or another. rkny "agnoscetur", Montanus, Vatablus; "cognoscetur", Tigurine version; "cognoscitur", Amama, so Luther. w "quamvis", Luther.
