And in a great house there are not only vessels of gold and of silver, but also of wood and of earth, and some to honour, and some to dishonour:

if, then, any one may cleanse himself from these, he shall be a vessel to honour, sanctified and profitable to the master -- to every good work having been prepared,

2 Timóteo 2:20,21

And we have this treasure in earthen vessels, that the excellency of the power may be of God, and not of us;

2 Coríntios 4:7

nay, but, O man, who are you that are answering again to God? shall the thing formed say to Him who did form it, Why me did you make thus?

has not the potter authority over the clay, out of the same lump to make the one vessel to honour, and the one to dishonour?

Romanos 9:20,21
