Psalm 41:1-3

To the Chief Musician. A Psalm of David.

1 Blessed is he who considers the poor;
      The LORD will deliver him in time of trouble.
2 The LORD will preserve him and keep him alive,
      And he will be blessed on the earth;
      You will not deliver him to the will of his enemies.
3 The LORD will strengthen him on his bed of illness;
      You will sustain him on his sickbed.

To "consider" in Hebrew is to look with understanding, be
circumspect.... not just an after thought.... for the poor. Our Lord's ministry
always go out to the poor, both in the economic sense, weak (women of Jesus
time, the outcast, lepers, gentiles, etc) and in spirit (humility &
meekness). Either sense of the word 'poor', there is a happiness
(blessedness) in store for those who not just give the poor an after thought but
take the necessary practical action.

What would be our happiness then?
We are led aright to safety, Psa 23:3 "He restores my soul; He leads me
in the paths of righteousness For His name's sake." God Himself will
assure our preservation and our descendents as well (Psa 25:13). God is
interested in giving us posterity, not just prosperity (permanency
rather than temporal). So much so our enemies will even see our lives having
the outflow of joy and praises to our Redeemer (Psa 27:6).

The bold statements of "The LORD (Jehovah, the Existing One) will..."
is our guarantee for He is not one who breaks vows. Therefore there
isn't any excuse for our generosity toward the poor.

The poor amongst us maybe even our 'enemies'. As Jesus didn't hold any
prejudices to all who come to Him to be made 'rich' (given a value,
healed, blessed, freed, etc), so we follow the steps of our master.
