1 Samuel 24:13

You will know them by their fruit; do men gather grapes from thorns or figs from thistles? No,

So you will know them by their fruit.

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

For out of the heart come evil designs, murder, adultery, sexual vice, stealing, false witness, and slander.

Treasury of Scripture Knowledge

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

You will know them by their fruit; do men gather grapes from thorns or figs from thistles? No,

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

For out of the heart come evil designs, murder, adultery, sexual vice, stealing, false witness, and slander.

while what comes out of the mouth comes from the heart ??and that is what defiles a man.
