Hebrews 3:12

Thus saith the LORD; Cursed be the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from the LORD.

But they hearkened not, nor inclined their ear, but walked in the counsels and in the imagination of their evil heart, and went backward, and not forward.

The heart is deceitful above all things, and desperately wicked: who can know it?

And they said, There is no hope: but we will walk after our own devices, and we will every one do the imagination of his evil heart.

Wherefore let him that thinketh he standeth take heed lest he fall.

See that ye refuse not him that speaketh. For if they escaped not who refused him that spake on earth, much more shall not we escape, if we turn away from him that speaketh from heaven:

Yet they obeyed not, nor inclined their ear, but walked every one in the imagination of their evil heart: therefore I will bring upon them all the words of this covenant, which I commanded them to do: but they did them not.

Now the just shall live by faith: but if any man draw back, my soul shall have no pleasure in him.

And ye have done worse than your fathers; for, behold, ye walk every one after the imagination of his evil heart, that they may not hearken unto me:

And Jesus answered and said unto them, Take heed that no man deceive you.

Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled;

For the turning away of the simple shall slay them, and the prosperity of fools shall destroy them.

Wherefore I was grieved with that generation, and said, They do alway err in their heart; and they have not known my ways.

Take ye heed, watch and pray: for ye know not when the time is.

At that time they shall call Jerusalem the throne of the LORD; and all the nations shall be gathered unto it, to the name of the LORD, to Jerusalem: neither shall they walk any more after the imagination of their evil heart.

For my people have committed two evils; they have forsaken me the fountain of living waters, and hewed them out cisterns, broken cisterns, that can hold no water.

Which said unto God, Depart from us: and what can the Almighty do for them?

For I have kept the ways of the LORD, and have not wickedly departed from my God.

And he said, Take heed that ye be not deceived: for many shall come in my name, saying, I am Christ; and the time draweth near: go ye not therefore after them.

For if God spared not the natural branches, take heed lest he also spare not thee.
