Job 28:2-6

2They know how to take iron from under the ground. They can also use heat to get copper from rocks.

3People take light into dark places under the ground. They look carefully for valuable metals.

4They dig deep holes in the ground far away from places where people live. Other people do not know about those places. People hang on ropes as they go deep down into the earth.

5We grow our food on the earth above. But deep under the ground, people use fire to break the rocks.

6Sapphires come from the rocks in those places. The dust there contains gold.
