Isaiah 36:7

The Rabshakeh knew about Hezekiah’s religious reforms in which he had removed many of the altars from the land (cf. 2 Kings 18:1-7; 2 Chronicles 29-31). Evidently the commander believed that removing altars would antagonize Yahweh, but Hezekiah was really purifying Yahweh worship. However, many of the Judeans probably believed that the removal of those altars was a bad thing, and it was to those people that the Rabshakeh was evidently appealing.
