As with many of Crusoe’s Biblical quotations, the Book of Job deals with righteousness, suffering and their rewards.

So the Lord blessed the latter end of Job more than his beginning: for he had fourteen thousand sheep, and six thousand camels, and a thousand yoke of oxen, and a thousand she asses. He had also seven sons and three daughters.

Job 42:12-13
