and the tongue that deceives.

Jeremiah 9:3-5

The Lord Laments That He Has No Choice But to Judge Them

9:3 The Lord says,

“These people are like soldiers who have readied their bows.

Their tongues are always ready to shoot out lies.

They have become powerful in the land,

but they have not done so by honest means.

Indeed, they do one evil thing after another

and do not pay attention to me.

9:4 Everyone must be on his guard around his friends.

He must not even trust any of his relatives.

For every one of them will find some way to cheat him.

And all of his friends will tell lies about him.

9:5 One friend deceives another

and no one tells the truth.

These people have trained themselves to tell lies.

They do wrong and are unable to repent.

Jeremiah 9:8

9:8 Their tongues are like deadly arrows.

They are always telling lies.

Friendly words for their neighbors come from their mouths.

But their minds are thinking up ways to trap them.

James 3:5-8

3:5 So too the tongue is a small part of the body, yet it has great pretensions. Think how small a flame sets a huge forest ablaze. 3:6 And the tongue is a fire! The tongue represents the world of wrongdoing among the parts of our bodies. It pollutes the entire body and sets fire to the course of human existence – and is set on fire by hell.

3:7 For every kind of animal, bird, reptile, and sea creature is subdued and has been subdued by humankind. 3:8 But no human being can subdue the tongue; it is a restless evil, full of deadly poison.
