2 Timothy 2:20-21 ESV  20 Now in a great house there are not only vessels of gold and silver but also of wood and clay, some for honorable use, some for dishonorable. 21 Therefore, if anyone cleanses himself from what is dishonorable, he will be a vessel for honorable use, set apart as holy, useful to the master of the house, ready for every good work.

1 Timothy 3:15 NASB  but in case I am delayed, I write so that you will know how one should act in the household of God, which is the church of the living God, the pillar and support of the truth.
