Proverbs 23:10-11

10 Do not move an ancient boundary stone or encroach on the fields of the fatherless,
11 for their Defender is strong; he will take up their case against you.

Like widows, God took special care of the fatherless, foreigner, and poor. The mighty God promised to come from heaven with vengeance on those who trouble these categories of the weak and helpless. It is wisdom and true religion to go out of your way to help them.

James 1:27 Religion that God our Father accepts as pure and faultless is this: to look after orphans and widows in their distress and to keep oneself from being polluted by the world.

Application

Have a meal with a fatherless / widow.
