Double-hearted: “a heart and a heart;” that is, as it were, with two hearts, one that gives utterance to the words, and the other that retains a different sentiment. Thus, in Deuteronomy 25:13, the phrase in Hebrew, “a stone and a stone” means, as it is translated, “divers weights” – one stone or weight to buy with, and another to sell with. So the flatterer. He has one heart to give utterance to the words which he uses toward his neighbor, and another that conceals his real purpose or design. No confidence, therefore, could be placed in such persons.
