God is a judge of the widows:

Psalms 68:5- A father of the fatherless, and a judge of the widows, is God in his holy habitation.

God protects Widows from those who would prey on them:

Isaiah 10:2- To turn aside the needy from judgment, and to take away the right from the poor of my people, that widows may be their prey, and that they may rob the fatherless!

God instructs Widows to trust in Him:

Jeremiah 49:11 - Leave thy fatherless children, I will preserve them alive; and let thy widows trust in me.

God pronounces woe to those who devour widows for hypocritical gain:

Matthew 23:14 Woe unto you, scribes and Pharisees, hypocrites! for ye devour widows' houses, and for a pretence make long prayer: therefore ye shall receive the greater damnation.

Jesus spoke of the widows in Elijah's Day:

The Early Church's first conflict came as a result of the neglect of widows:

Acts 6:1 - And in those days, when the number of the disciples was multiplied, there arose a murmuring of the Grecians against the Hebrews, because their widows were neglected in the daily ministration.

Widows in the early church were great intercessors with a heart of humility and contrition: 

Acts 9:39- Then Peter arose and went with them. When he was come, they brought him into the upper chamber: and all the widows stood by him weeping, and showing the coats and garments which Dorcas made, while she was with them.

Widows were mentioned along with saints in the early church:

 Acts 9:41- And he gave her his hand, and lifted her up, and when he had called the saints and widows, presented her alive.

Paul addressed widows concerning marriage in his letter to the Corinthians:

 1 Corinthians 7:8 - I say therefore to the unmarried and widows, It is good for them if they abide even as I.

We are commanded to HONOR widows who are widows indeed:

1 Timothy 5:3- Honor widows that are widows indeed.

We are to discerning of those widows who wax wanton against Christ:

1 Timothy 5:11- But the younger widows refuse: for when they have begun to wax wanton against Christ, they will marry;

We are commanded to RELIEVE widows of burdens:

1 Timothy 5:16 - If any man or woman that believeth have widows, let them relieve them, and let not the church be charged; that it may relieve them that are widows indeed.

Ministry to the widows proves whether our religion is pure and undefiled:

James 1:27- Pure religion and undefiled before God and the Father is this, To visit the fatherless and widows in their affliction, and to keep himself unspotted from the world.
