'Priceless' in the Bible

Great and priceless treasure is in the house of the [consistently] righteous one [who seeks godly instruction and grows in wisdom],But trouble is in the income of the wicked one [who rejects the laws of God].

“Everyone who thirsts, come to the waters;And you who have no money come, buy grain and eat.Come, buy wine and milkWithout money and without cost [simply accept it as a gift from God].
