Deuteronomy 11:16

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

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

"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. let...: Gr. run out as leaking vessels"

"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;"

"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."

"And take heed to yourselves, lest at any time your hearts be overcharged with surfeiting, and drunkenness, and cares of this life, and so that day come upon you unawares."

"But if thine heart turn away, so that thou wilt not hear, but shalt be drawn away, and worship other gods, and serve them;"

"He feedeth on ashes: a deceived heart hath turned him aside, that he cannot deliver his soul, nor say, Is there not a lie in my right hand?"

"And it shall be, if thou do at all forget the LORD thy God, and walk after other gods, and serve them, and worship them, I testify against you this day that ye shall surely perish."

"Little children, keep yourselves from idols. Amen."
