30 For the people of Judah have done evil in my sight, says the Lord; they have set their abominations in the house that is called by my name, defiling it. 31 And they go on building the high place of Topheth, which is in the valley of the son of Hinnom, to burn their sons and their daughters in the fire-which I did not command, nor did it come into my mind. 32 Therefore, the days are surely coming, says the Lord, when it will no more be called Topheth, or the valley of the son of Hinnom, but the valley of Slaughter: for they will bury in Topheth until there is no more room. 33 The corpses of this people will be food for the birds of the air, and for the animals of the earth; and no one will frighten them away. 34 And I will bring to an end the sound of mirth and gladness, the voice of the bride and bridegroom in the cities of Judah and in the streets of Jerusalem; for the land shall become a waste.

Commentary on Jeremiah 7:29-34

(Read Jeremiah 7:29-34)

In token both of sorrow and of slavery, Jerusalem must be degraded, and separated from God, as she had been separated to him. The heart is the place in which God has chosen to put his name; but if sin has the innermost and uppermost place there, we pollute the temple of the Lord. The destruction of Jerusalem appears here very terrible. The slain shall be many; they having made it the place of their sin. Evil pursues sinners, even after death. Those who will not, by the grace of God, be cured of vain mirth, shall, by the justice of God, be deprived of all mirth. How many ruin their health and property without complaining, when engaged in Satan's service! May we learn to relish holy joys, and to sit loose to all others though lawful.
