Throughout much of this Psalm, including this section, David provides us with many examples of Godly living. For example, verses 129 and 131 talk about loving God’s word, and verse 130 talks about why its important to study God’s word because it gives us insight into the character of God and also gives us understanding. In verse 133, David prays that God will work through him – I think that this is one of God’s great blessing. In verse 135, David refers to himself as God’s servant, which is very much an act of humility considering that David was a king. There are many other examples, but the point is that I think that David provides a great model for Godly living.
