David, being oppressed, is here waiting and wishing for the salvation
of the Lord, which would make him easy. 1. He cannot but think that it
comes slowly: My eyes fail for thy salvation. His eyes were towards it
and had been long so. He looked for help from heaven (and we deceive
ourselves if we look for it any other way), but it did not come so soon
as he expected, so that his eyes began to fail, and he was sometimes
ready to despair, and to think that, because the salvation did not come
when he looked for it, it would never come. It is often the infirmity
even of good men to be weary of waiting God's time when their time has
elapsed. 2. Yet he cannot hope that it comes surely; for he expects the
word of God's righteousness, and no other salvation than what is
secured by that word, which cannot fall to the ground because it is a
word of righteousness. Though our eyes fail, yet God's word does not,
and therefore those that build upon it, though now discouraged, shall
in due time see his salvation.
