The previous three stanzas of Psalm 119 emphasized drawing near to God. In verses 121-136 we do not find the cry of a proud person looking over his domain. Instead, a different cry arises, that of a servant.
(122) Ensure your servants well-being is a cry for God to take up the psalmist’s cause, for God to represent him. Christ ensures his followers are heard by interceding on our behalf (Hebrews 7:23-28). The Holy Spirit also intercedes for those who are God’s people (Romans 8:26-27).
The servant asks for God to (124) deal with them mercifully, (125) give them understanding, (128) and keep them from the wrong path.
What does the right path look like? (130) Unfold your words is the preparing one’s heart to receive the light of God’s word. It involves turning towards (not away from) the God of mercy. Those committed to the right path ask Him to direct their footsteps (133), deliver them from oppression (134) and shine on them (135).
If you find yourself on the right path do not be surprised if (136) streams of tears flow from your eyes when you observe those around you who are hostile towards the Savior they do not know personally.
