2 Kings 23:6

“Now it will be on the day you go out and cross over the brook Kidron, that you will know for certain that you shall surely die; your blood shall be on your own head.”

Then he put the graven image of Asherah, which he had made, in the house of which Yahweh had said to David and to Solomon his son, “In this house and in Jerusalem, which I have chosen from all the tribes of Israel, I will put My name forever.

Also, the altars which were on the roof, the upper chamber of Ahaz, which the kings of Judah had made, and the altars which Manasseh had made in the two courts of the house of Yahweh, the king tore down; and he crushed them there and threw their dust into the brook Kidron.

Furthermore, the altar that was at Bethel and the high place which Jeroboam the son of Nebat, who made Israel sin, had made, even that altar and the high place he tore down. Then he demolished its stones, ground them to dust, and burned the Asherah.

Indeed, he rebuilt the high places which Hezekiah his father had torn down; and he erected altars for the Baals and made Asherim, and worshiped all the host of heaven and served them.

“And the whole valley of the dead bodies and of the ashes, and all the fields as far as the brook Kidron, to the corner of the Horse Gate toward the east, shall be holy to Yahweh; it will not be uprooted or pulled down anymore forever.”

When Jesus had spoken these words, He went forth with His disciples to the other side of the Kidron Valley, where there was a garden, into which He entered with His disciples.
