1 Samuel 24:13

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

By their fruits ye shall know them. Do men gather a bunch of grapes from thorns, or from thistles figs?

By their fruits then surely ye shall know them.

Either make the tree good, and its fruit good; or make the tree corrupt, and its fruit corrupt. For from the fruit the tree is known.

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

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

By their fruits ye shall know them. Do men gather a bunch of grapes from thorns, or from thistles figs?

Either make the tree good, and its fruit good; or make the tree corrupt, and its fruit corrupt. For from the fruit the tree is known.

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

His mischief shall return upon his own head, and his violence shall come down upon his own pate.

Let integrity and uprightness preserve me; for I wait on thee.

but the things which go forth out of the mouth come out of the heart, and those defile man.
