Therefore we ought to give the more earnest heed to the things which we have heard, lest at any time we should let them slip.

Take heed, brethren, left there be in any of you an evil heart of unbelief, in departing from the living God:

But exhort one another daily, while it is called to day, lest any of you be hardened through the deceitfulness of sin:

Let us therefore fear, lest a promise being left us of entring into his rest, any of us should altogether come short of it.

Let us labour, therefore, to enter into that rest, lest any one should fall, after the same example of unbelief.

For the word of God is living and powerful, and sharper than any two edged sword, piercing even to the dividing asunder both of the soul and spirit, both of the joints and marrow, and is a discerner of the thoughts and intents of the heart.

Neither is there any creature that is not manifest in his sight; but all things are naked and opened to the eyes of him with whom we have to do.

Looking diligently, lest any one fall from the grace of God, lest any root of bitterness springing up trouble you, and thereby many be defiled: Lest there be any fornicator or profane person,

and blackness, and darkness, and tempest, And the sound of a trumpet, and the voice of words, which they that heard intreated that the word might not be spoken to them any more.
