King James Dictionary

Supplant To deceive; defraud. And they bend their tongues like their bow for lies: but they are not valiant for the truth upon the earth; for they proceed from evil to evil, and they know not me, saith the LORD. Take ye heed every one of his neighbour, and trust ye not in any brother: for every brother will utterly SUPPLANT, and every neighbour will walk with slanders. And they will deceive every one his neighbour, and will not speak the truth: they have taught their tongue to speak lies, and weary themselves to commit iniquity. (Jer 9,5)
