Jeremiah 19:1, “Thus says the Lord: Go and get a potter’s earthen bottle, and take some of the old people and some of the elderly priests…”
Why did he ask for the elderly? Was this a special word just for them?
“Ancients – elderly. As witnesses of the symbolic action (v. 10; Isaiah 8:1, 2), that the Jews might not afterwards plead ignorance of the prophecy. The seventy-two elders, composing the Sanhedrin, or Great Council, were partly taken from “the priests,” partly from the other tribes, i.e. “the people,” the former presiding over spiritual matters, the later over the civil. The seventy-two represented the whole people.”
God wanted the leadership to know what He was going to do.
