91 If only my head were a pool of water and my eyes a fountain of tears, I would weep day and night for all my people who have been slaughtered. 2 Oh, that I could go away and forget my people and live in a travelers' shack in the desert. For they are all adulterers- a pack of treacherous liars. 3 "My people bend their tongues like bows to shoot out lies. They refuse to stand up for the truth. They only go from bad to worse. They do not know me," says the Lord . 4 "Beware of your neighbor! Don't even trust your brother! For brother takes advantage of brother, and friend slanders friend. 5 They all fool and defraud each other; no one tells the truth. With practiced tongues they tell lies; they wear themselves out with all their sinning. 6 They pile lie upon lie and utterly refuse to acknowledge me," says the Lord . 7 Therefore, this is what the Lord of Heaven's Armies says: "See, I will melt them down in a crucible and test them like metal. What else can I do with my people? 8 For their tongues shoot lies like poisoned arrows. They speak friendly words to their neighbors while scheming in their heart to kill them. 9 Should I not punish them for this?" says the Lord . "Should I not avenge myself against such a nation?" 10 I will weep for the mountains and wail for the wilderness pastures. For they are desolate and empty of life; the lowing of cattle is heard no more; the birds and wild animals have all fled. 11 "I will make Jerusalem into a heap of ruins," says the Lord . "It will be a place haunted by jackals. The towns of Judah will be ghost towns, with no one living in them."

Commentary on Jeremiah 9:1-11

(Read Jeremiah 9:1-11)

Jeremiah wept much, yet wished he could weep more, that he might rouse the people to a due sense of the hand of God. But even the desert, without communion with God, through Christ Jesus, and the influences of the Holy Spirit, must be a place for temptation and evil; while, with these blessings, we may live in holiness in crowded cities. The people accustomed their tongues to lies. So false were they, that a brother could not be trusted. In trading and bargaining they said any thing for their own advantage, though they knew it to be false. But God marked their sin. Where no knowledge of God is, what good can be expected? He has many ways of turning a fruitful land into barrenness for the wickedness of those that dwell therein.
