Boaz took an active role in being the redeemer far before he has the actual title, he set the wheels in motion and arranged the elders to meet with himself and the man with greater rights.
Naomi has been blessed by Ruth, and we see here she wants to bless Ruth as well by securing her future in a marriage. Naomi then lays out the seemingly bizarre procedure to Ruth to begin this process, which Ruth trusts implicitly and immediately goes and executes on, and is blessed by the success of the result of that initial trust, and action.
Ruth Chapter 2 introduces the man Boaz as being related to Elimelech, a relative in a position to redeem Naomi (redeemer=go'el). In this case Boaz reserved the right if he was found to be the closest living relative to buy and redeem the land that once belonged to Naomi back into her possession. God is also referred to as "go'el" redeemer, as redeemer of Israel, and personal redeemer.
Here is the JJ weeks band/Colton Dixon song mentioned in my Ruth 1 post that really illustrates the idea of letting God work through you to the point that people can see something different about you, hopefully so much so that they want to find out more!
Ruth begins with the words "In the days the judges ruled" - these were dark times illustrated by a cycle of sin by the people which would lead to God's judgement and enemies sent against them, to the cry of those people to God for help, to God raising up a judge to rescue them.
SCHIN The repetition of v. 163 struck me, for the psalmist to say both "hate" and "abhor" it provides a stronger sense of just how strong that hatred is. Abhor is defined as "regard with disgust and hatred", or "to shudder away from".
KOPH The psalmist shows his reliance on the Lord here with the "dawn to dusk" approach to seeking God, he seeks Him every waking hour "hoping in His words" and "meditating on His promise". I need to try not to seek the Lord only when it is convenient for me, but instead remember to seek Him in all those times in-between, for all sorts of reasons, not just in need.
PE God's words are the light in our darkness, and as complex as He is, they have been given to us in a way that we can understand. Praying to God to be merciful is something we all want God to grace us with, yet when we actually stop and think of the mercy and justice we have earned, it may be less appealing to think of what judgements we have brought upon ourselves.
SAMECH In the ESV translation it says "double-minded" instead of "vain". God doesn't want us to be luke-warm in our faith to Him (1 Kings 18:21, Rev 3:15-16). I heard a message recently that said this: "As a gardener you can't just love the flowers, you have to hate the weeds".
MEM The psalmist has devoted himself and his life to the study of God's word, it is the highest in his heart as we see the devotion and love he has for it. It is the sword and shield against those who come against him, as God will always get the upper hand, simply being an enemy of the psalmist is also being an enemy of God, not a wise choice.
