Deuteronomy

If any man among you seem to be religious, and bridleth not his tongue, but deceiveth his own heart, this man’s religion is vain.

Lest there should be among you man, or woman, or family, or tribe, whose heart turneth away this day from the Lord our God, to go and serve the gods of these nations; lest there should be among you a root that beareth gall and wormwood;

And thou shalt not go aside from any of the words which I command thee this day, to the right hand, or to the left, to go after other gods to serve them.

And my heart hath been secretly enticed, or my mouth hath kissed my hand:

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