When he speaketh fair - For there are such hypocrites and false friends in the world.
Believe him not - Let all his professions go for nothing.
For there are seven abominations in his heart - That is, he is full of abominations.
Seven abominations - Compare Proverbs 26:16 note. Here “seven” retains, perhaps, its significance as the symbol of completeness. Evil has, as it were, gone through all its work, and holds its accursed Sabbath in the heart in which all things are “very evil.”
