A lying tongue hateth those that are afflicted by it; and a flattering mouth worketh ruin.
-Pro 26:28
Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him.
-1Jo 3:15
It's not just hatred; once you connect the verses, God says that afflicted (i.e. grieving or paining) others with lies is the equivalent of murder in His sight.
