91 Oh that my head were waters, and mine eye 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 traveller's lodging-place, that I might leave my people, and go away from them! For they are all adulterers, an assembly of treacherous men. 3 And they bend their tongue, their bow of falsehood, and not for fidelity are they valiant in the land; for they proceed from evil to evil, and they know not me, saith Jehovah. 4 Take ye heed every one of his friend, and confide not in any brother; for every brother only supplanteth, and every friend goeth about with slander. 5 And they act deceitfully every one with his neighbour, and speak not the truth: they teach their tongue to speak falsehood, they weary themselves with perverse dealing. 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 could I do for the daughter of my people? 8 Their tongue is a murderous arrow; it speaketh deceit. [A man] speaketh peaceably to his neighbour with his mouth, but in his heart he layeth his ambush. 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 weeping and wailing, and for the pastures of the wilderness, a lamentation; for they are burnt up, so that none passeth through them; and the voice of the cattle is not heard. Both the fowl 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.
