1 This Psalm, a short one, which demands an analytical rather than a homiletical treatment, teaches us the lesson of humility and meekness. Now, as we have in a great number of other places spoken about humility, there is no need to repeat the same things here. Of course we are bound to bear in mind in how great need our faith stands of humility when we hear the Prophet thus speaking of it as equivalent to the performance of the highest works: O Lord, my heart is not exalted. For a troubled heart is the noblest sacrifice in the eyes of God. The heart, therefore, must not be lifted up by prosperity, but humbly kept within the bounds of meekness through the fear of God.
