1 Peter 2:1

The holy apostle has been recommending mutual charity, and setting forth the excellences of the word of God, calling it an incorruptible seed, and saying that it liveth and abideth for ever. He pursues his discourse, and very properly comes in with this necessary advice, Wherefore laying aside all malice, etc. These are such sins as both destroy charity and hinder the efficacy of the word, and consequently they prevent our regeneration. I. His advice is to lay aside or put off what is evil, as one would do an old rotten garment: "Cast it away with indignation, never put it on more." 1. The sins to be put off, or thrown aside, are, (1.) Malice, which may be taken more generally for all sorts of wickedness, as Jam 1:21; Co1 5:8. But, in a more confined sense, malice is anger resting in the bosom of fools, settled overgrown anger, retained till it inflames a man to design mischief, to do mischief, or delight in any mischief that befalls another. (2.) Guile, or deceit in words. So it comprehends flattery, falsehood, and delusion, which is a crafty imposing upon another's ignorance or weakness, to his damage. (3.) Hypocrisies. The word being plural comprehends all sorts of hypocrisies. In matters of religion hypocrisy is counterfeit piety.
