Proverbs 23:4 Labour not to be rich: cease from thine own wisdom.
5 Wilt thou set thine eyes upon that which is not? for riches certainly make themselves wings; they fly away as an eagle toward heaven.
These two verse help to understand that we do not need to labor constantly trying to get more riches on this earth. We came into this world with nothing and we will leave with nothing of this world. When people come into a lot of money at one time it is usually gone just as fast and they are in worst shape before they had what they received. We should be more concentrated on gaining wisdom and knowledge from God and let Him supply our needs as He can from His riches and also wait for greatest riches which is eternity in Heaven with Him.
