Spurgeon · Verse 7
He that worketh deceit shall not dwell within my house. He had power to choose his courtiers, and he meant to exercise it. Deceit among most orientals is reckoned to be a virtue, and is only censured when it is not sufficiently cunning, and therefore comes to be found out; it was therefore all the more remarkable that David should have so determinedly set his face against it. He could not tell what a deceitful man might be doing, what plots he might be contriving, what mischief he might be brewing, and therefore he resolved that he would at any rate keep him out of his house, that his palace might not become a den of villainy. Cheats in the market are bad enough, but deceivers at our own table we cannot bear. He that telleth lies shall not tarry in my sight. He would not have a liar within sight or hearing; lie loathed the mention of him. Grace makes men truthful, and creates in them an utter horror of everything approaching to falsehood. If David would not have a liar in his sight, much less will the Lord; neither he that loves nor he who makes a lie shall be admitted into heaven. Liars are obnoxious enough on earth; the saints shall not be worried with them in another world.
