1 Timothy 3:5; 1 Timothy 3:15; 1 Timothy 5:16

5 (but if a man does not know how to manage his own household, how will he take care of the church of God?),

15 but in case I am delayed, I write so that you will know how one ought to conduct himself in the household of God, which is the church of the living God, the pillar and support of the truth.

16 If any woman who is a believer has dependent widows, she must assist them and the church must not be burdened, so that it may assist those who are widows indeed.
