Jeremiah 9:5 Meaning and Commentary

Jeremiah 9:5

And they will deceive everyone his neighbour
In conversation, with lying words; and in trade and commerce, by art and tricking: and will not speak the truth;
with respect to facts they report, or goods they sell: they have taught their tongue to speak lies;
and become so accustomed to lying that they cannot do otherwise; it is as it were natural to them: and weary themselves to commit iniquity;
spared no pains to come at it, nor any in it, and go on even to weariness; are more laborious and indefatigable in committing sin than good men are in doing good; which shows great folly and stupidity. The Targum is,

``they are become foolish, they have erred.''

Jeremiah 9:5 In-Context

3 "They get ready to use their tongues like bows," announces the Lord. "Their mouths shoot out lies like arrows. They tell lies to gain power in the land. They go from one sin to another. They do not pay any attention to me.

4 Be on guard against your friends. Do not trust the members of your own family. Every one of them cheats. Every friend tells lies.

5 One friend cheats another. No one tells the truth. They have taught their tongues how to lie. They wear themselves out sinning.

6 Jeremiah, you live among people who tell lies. When they lie, they refuse to pay any attention to me," announces the Lord.

7 So the LORD who rules over all says, "I will put them through the fire to test them. What else can I do? My people are so sinful!
