Psalm 41

Jesus told his disciples to treat other people as they wished to be treated (Matt. 7:12) and to love their neighbors as they love themselves (Matt. 22:39).  David said that God's attention, and subsequent deliverence, was on those who kept his attention of the weak. The ESV uses the word "poor". Regardless of which word may offer the best translation I believe God wants his people not to turn away from those who are the most vulnerable in our society.
It took me about 1 minute to read this psalm.
