Yellow and white guts and garbage

(Thomas Brooks, "The Crown and Glory of Christianity,
 or, HOLINESS, the Only Way to Happiness", 1662)

"You cannot serve both God and Money." Luke 16:13

Riches are the great god of the world, and are rather a
hindrance, than a help to heaven and happiness. Gold
and silver, which are but the yellow and white guts
and garbage of the earth, is fitly called by the prophet,
"thick clay," which will sooner break a man's back than
satisfy his heart! Oh, what folly and madness is it for a
man to be still a-loading of himself with the clay of this
world!

Though the horse is loaded with rich treasure all the
day long—yet when night comes he is turned into the
dark stinking stable, with an empty belly, and with
his back full of galls, sores, and bruises.

Just so, though vain muckworms are loaded with the
treasures of this world during the day of their life—
yet when the night of death comes, then they shall
be turned into a dark stinking hell, with consciences
full of guilt and galls, and with souls full of sores and
bruises; and then what good will all their treasures
do them?

"People who want to get rich fall into temptation and
 a trap and into many foolish and harmful desires that
 plunge men into ruin and destruction. For the love
 of money is a root of all kinds of evil. Some people,
 eager for money, have wandered from the faith and
 pierced themselves with many griefs." 1 Tim. 6:9-10
