TRUTH Jeremiah 9:4-6

"Beware of your friends; do not trust anyone in your clan, for every one of them is a deceiver, and every friend a slanderer. Friend deceives friend, and no one speaks the truth. They have taught their tongues to lie; they weary themselves with sinning. You live in the midst of deception; in their deceit they refuse to acknowledge me," declares the LORD.

Beware of your friends 
2 Samuel 15:12  While Absalom as offering sacrifices, he also sent for Ahithophel the Gilonite, David's counselor, to come from Giloh, his hometown. And so the conspiracy gained strength, and Absalom's following kept on increasing.

do not trust anyone in your clan 
Micah 7:5-6  Do not trust a neighbor; put no confidence in a friend. Even with the woman who lies in your embrace guard the words of your lips. For a son dishonors his father, a daughter rises up against her mother, a daughter-in-law against her mother-in-law--a man;'s enemies are the members of his own household.

For every one of them is a deceiver
Genesis 27:35  But he said, "Your brother came deceitfully and took your blessing." 

and every friend a slanderer 
Exodus 20:16  "You shall not give false testimony against your neighbor." 
Leviticus 19:16  " 'Do not go about spreading slander among your people. Do not do anything that endangers your neighbor's life. I am the LORD.' "

Friend deceives friend 
Leviticus 6:2  "If anyone sins and is unfaithful to the LORD by deceiving a neighbor about something entrusted to them or left in their care or about something stolen, or if they cheat their neighbor, ..." (continued in verses 3-7) 

and no one speaks the truth 
Psalm 15:2  The one whose walk is blameless, who does what is righteous, who speaks the truth from their heart; ...
Isaiah 59:15  Truth is nowhere to be found, and whoever shuns evil becomes a prey. The LORD looked and was displeased that there was no justice.

They have taught their tongues to lie 
Psalm 52:3  You love evil rather than good, falsehood rather than speaking the truth.

You live in the midst of deception 
Jeremiah 5:27-28  "Like cages full of birds, their houses are full of deceit; they have become rich and powerful and have grown fat and sleek. Their evil deeds have no limit; they do not seek justice. They do not promote the case of the fatherless; they do not defend the just cause of the poor."
