1 Timothy 5:11-16

As for younger widows, do not put them on such a list. For when their sensual desires overcome their dedication to Christ, they want to marry. Thus they bring judgment on themselves, because they have broken their first pledge. Besides, they get into the habit of being idle and going about from house to house. And not only do they become idlers, but also busybodies who talk nonsense, saying things they ought not to. So I counsel younger widows to marry, to have children, to manage their homes and to give the enemy no opportunity for slander. Some have in fact already turned away to follow Satan. 
If any woman who is a believer has widows in her care, she should continue to help them and not let the church be burdened with them, so that the church can help those widows who are really in need. 

And not only do they become idlers, but also busybodies 
2 Thessalonians 3:11  We hear that some among you are idle and disruptive. They are not busy; they are busybodies.

So I counsel younger widows to marry 
1 Corinthians 7:9  But if they cannot control themselves, they should marry, for it is better to marry than to burn with passion.

and to give the enemy no opportunity for slander 
1 Timothy 6:1  All who are under the yoke of slavery should consider their masters worthy of full respect, so that God's name and our teaching may not be slandered.

Some have in fact already turned away to follow Satan 
Matthew 16:23  Jesus turned and said to Peter, "Get behind me, Satan! You are a stumbling block to me; you do not have in mind the concerns of God, but merely human concerns."
1 John 3:8  The one who does what is sinful is of the devil, because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the devil's work.
Revelation 12:9  The great dragon was hurled down--that ancient serpent called the devil, or Satan, who leads the whole world astray. He was hurled to the earth, and his angels with him.

so that the church can help those widows who are really in need 
1 Timothy 5:3-5  Give proper recognition to those widows who are really in need. But if a widow has children or grandchildren, these should learn first of all to put their religion into practice by caring for their own family and so repaying their parents and grandparents, for this is pleasing to God. The widow who is really in need and left all alone puts her hope in God and continues night and day to pray and to ask God for help.
