1 Samuel 24:13

As the ancient proverb says, Wickedness proceeds from the wicked. But my hand shall not be on you.

You shall know them by their fruits. Do men gather grapes from thorns, or figs from thistles?

Therefore by their fruits you shall know them.

Either make the tree good and its fruit good, or else make the tree corrupt and its fruit corrupt; for the tree is known by its fruit.

For out of the heart come evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies;

As saith the proverb of the ancients, Wickedness proceedeth from the wicked: but mine hand shall not be upon thee.

You shall know them by their fruits. Do men gather grapes from thorns, or figs from thistles?

Either make the tree good and its fruit good, or else make the tree corrupt and its fruit corrupt; for the tree is known by its fruit.

For out of the heart come evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies;

His mischief shall return on his own head, and his violence shall come on his own crown.

Let purity and uprightness keep me; for I wait on You.

But the things which come out of the mouth come from the heart, and they defile the man.
