Proverbs 13:25 The righteous eats to the satisfying of his soul: but the belly of the wicked shall want. 

‘The righteous eats to the satisfying of his soul: but the belly of the wicked shall want.’ The righteous are content with moderate desires and pleased with their lot in life, but the wicked are never satisfied.

All classes of the wicked are like the troubled sea that cannot be still and constantly stirs up the mire and dirt of sin and corruption. They have no peace (Isa. 57:20-21), no calmness of soul or spirit; their passions and appetites keep them in continual turmoil seeking something satisfying; the wealth, business, pleasure, pride, pomp, flattery, and unrest of the world only keep them dissatisfied; and strong undercurrents of malice, jealousy, lust, revenge, strife, and ambitions to outdo others keep them at war with God and fellowmen. The guilt of a past life and the burning memories of wrongdoing agitate the sinner day and night to cover up his evil, but he cannot escape the fear of hell and future reaping.
