During his visitation he saw a most beautifully designed altar that was in Damascus, and King Achaz desired to make a replica of it in Jerusalem.

The old copper altar shall only be used by me on occasion when I decide. Uriah the priest followed all of the instructions that King Achaz had commanded him.
- Achaz makes structural changes to the temple: King Achaz cut off the foundations of the sinks, and he removed the tank off the copper cattle that were under it, and put it on a stone floor.
