Covetousness is prohibited by the tenth commandment and addressed by Jesus in Luke 12 and by the writer of Hebrews.
In Exodus 20:17:
17 Thou shalt not covet thy neighbour’s house, thou shalt not covet thy neighbour’s wife, nor his manservant, nor his maidservant, nor his ox, nor his ass, nor any thing that is thy neighbour’s.
In Luke 12:15:
15 And he said unto them, Take heed, and beware of covetousness: for a man’s life consisteth not in the abundance of the things which he possesseth.
In Hebrews 13:5:
5 Let your conversation be without covetousness; and be content with such things as ye have: for he hath said, I will never leave thee, nor forsake thee.
