We must start looking for ways to feed the poor and those who need financial support and can't even share their need.
Not feeding the poor: This one, mentioned in the verse 18 of the Chapter, is one of the key elements.
Honoring the orphan can mean helping them morally, emotionally and of course financially.
Not honoring the orphan: In the verse 17, God tells humans that they are not as active as they should be when it comes to honoring the orphan.
