91 Oh that my head were waters, and mine eyes a fountain of tears, that I might weep day and night for the slain of the daughter of my people! 2 Oh that I had in the wilderness a lodging-place of wayfaring men; that I might leave my people, and go from them! for they are all adulterers, an assembly of treacherous men. 3 And they bend their tongue, [as it were] their bow, for falsehood; and they are grown strong in the land, but not for truth: for they proceed from evil to evil, and they know not me, saith Jehovah. 4 Take ye heed every one of his neighbor, and trust ye not in any brother; for every brother will utterly supplant, and every neighbor will go about with slanders. 5 And they will deceive every one his neighbor, and will not speak the truth: they have taught their tongue to speak lies; they weary themselves to commit iniquity. 6 Thy habitation is in the midst of deceit; through deceit they refuse to know me, saith Jehovah. 7 Therefore thus saith Jehovah of hosts, Behold, I will melt them, and try them; for how [else] should I do, because of the daughter of my people? 8 Their tongue is a deadly arrow; it speaketh deceit: one speaketh peaceably to his neighbor with his mouth, but in his heart he layeth wait for him. 9 Shall I not visit them for these things? saith Jehovah; shall not my soul be avenged on such a nation as this? 10 For the mountains will I take up a weeping and wailing, and for the pastures of the wilderness a lamentation, because they are burned up, so that none passeth through; neither can men hear the voice of the cattle; both the birds of the heavens and the beasts are fled, they are gone. 11 And I will make Jerusalem heaps, a dwelling-place of jackals; and I will make the cities of Judah a desolation, without inhabitant.

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.
