Jeremiah 7:12
But go ye now unto my place which was in Shiloh, where I set my name at the first, and see what I did to it for the wickedness of my people Israel. But go ye now unto my place which was in Shiloh, where I set my name at the first, and see what I did to it for the wickedness of my people Israel.
As part of the message in Jeremiah 7:1-14, the call to go to Shiloh directs Judah and Jerusalem to look at the place where God first set His name as a warning. Shiloh had been ruined and brought to calamity for the wickedness of Israel. That calamity included defeat by the Philistines, the loss of the ark, the death of Eli and his sons, and the killing of many people.
The ruin was allowed because wrongdoing flourished, including Eli's failure to correct the sins of his sons and other evils among the people. Having been chosen, having the sanctuary and God's name set there, and maintaining sacred places, religious services, and temple observance do not protect a place or people from just punishment when they persist in sin and wickedness. The presence of the sanctuary did not shield Shiloh, and Judah's observance of temple services would not shield it from judgment.
The same warning applies to unfaithfulness among those entrusted with positions of responsibility and trust in God's work. It meets neglect of God's principles, indulgence of selfishness, abandonment of self-denial and self-sacrifice, and reliance on human wisdom, their own ideas, and the imagination of their own hearts instead of divine wisdom and power. Such a course brings danger and serious consequences, so leaders must not follow their own hearts but must face the need for repentance and confession.
