Jeremiah 9:3-5

Wycliffe Bible

³ and they held forth their tongue as a bow of leasing, and not of truth. They be comforted in (the) earth, for they went out from evil to evil, and they knew not me, saith the Lord. (and they put forth their tongues like bows sending out lies, and not truth. They be made comfortable on the earth, as they go from evil to evil, and they do not even know me, saith the Lord.)

⁴ Each man keep him(self) from his neighbour, and have no trust in any brother of him; for why each brother deceiving shall deceive, and each friend shall go guilefully (for each brother shall deceive, and each friend shall be deceitful).

⁵ And a man shall scorn his brother, and shall not speak truth; for they taught their tongue to speak leasing; they travailed to do wickedly. (And a man shall mock his brother, and shall not speak the truth; for they taught their tongues to speak lies; they laboured to do wickedly.)
