Jeremiah 9:4 in the World English Bible
“Everyone beware of his neighbor, and don’t trust in any brother; for every brother will utterly supplant, and every neighbor will go around like a slanderer.
Context
3 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.
4 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.
5 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.
