2 Chronicles - Chapter 4

This chapter begins:

"Solomon also made a bronze altar 30 feet long, 30 feet wide, and 15 feet high."

The altar was the place of sacrifice and of death.  It was the first thing to be seen on entering the temple.  And in the temple it was much bigger than in the tabernacle.  Not only was it enormous, but it was high - 15 feet high.  When people watched a lamb being sacrificed they had to look up.

And this was a symbol of Jesus, the sacrificial lamb of God who takes away the sins of the world.  Jesus says this about his death in John 12:

""The time for judging this world has come, when Satan, the ruler of this world, will be cast out. And when I am lifted up from the earth, I will draw everyone to myself.” He said this to indicate how he was going to die."
