A psalm of David

1 Blessed are those who have regard for the weak;
  the LORD delivers them in times of trouble.
2 The LORD protects and preserves them—
  they are counted among the blessed in the land—
  he does not give them over to the desire of their foes.
3 The LORD sustains them on their sickbed
  and restores them from their bed of illness.

Psalm 41:1-3
