Proverbs 15:26, Thoughts Are The Index Of Character!
The contrast here is between the thoughts of the evil and the words of the pure. These thoughts are said to be an abomination to the Lord, while the words of pleasantness (marg.) are acceptable. Perowne points out that, according to Maurer, there may be a sacrificial meaning intended because of the reference in Malachi to a pure offering (1:11). Calvin and others believe the pure offering is not something happening at the time of the prophet, but is yet future, when the heathen are received into the kingdom of God (K-D).
