Lo, this is the man that made not God his strength; but trusted in the abundance of his riches, and strengthened himself in his wickedness. Made not God his strength - Did not make God his portion.
In the abundance of his riches - Literally, in the multiplication of his riches. He had got much, he hoped to get more, and expected that his happiness would multiply as his riches multiplied. And this is the case with most rich men.
Strengthened himself in his wickedness - Loved money instead of God; and thus his depravity, being increased, was strengthened.
Crescit amor nummi, quantum ipsa pecunia crescit.
"In proportion to the increase of wealth, so is the love of it."
Where is the religious man, in whose hands money has multiplied, who has not lost the spirit of piety in the same ratio? To prevent this, and the perdition to which it leads, there is no way but opening both hands to the poor.
