As we noted in yesterday's study, Luther made a strong point of indicating that the Word gives understanding “to the simple.” How this works is illustrated by the way Jesus dealt with the Emmaus disciples in the story recorded in Luke 24. These two people, probably Cleopas and his wife, Mary, were returning home after the crucifixion when Jesus drew near them on the road. They did not recognize him. When he asked why they were downcast they replied by telling him what had happened in Jerusalem at the time of the Passover. 

These stanzas offer seven reasons why God's words are wonderful, and the first is because they give “understanding to the simple.” The writer states this in verse 130 and records his obedient response in verse 131:

The entrance of your words gives light; it gives understanding to the simple.

I open my mouth and pant, longing for your commands. 

Many good things from the past are disappearing in today's modern and postmodern society, and one of them is wonder. People used to have their sense of awe incited by some new or unexpected thing. They had expressions like “wonder worker," "seven-day wonder” and “wonders never cease.” They read books like Alice's Adventures in Wonderland or watched movies like It's a Wonderful Life. Nothing seems wonderful any more. There is no mystery in anything. Everything seems commonplace, predictable and dull. 

The last two verses of this section repeat a point we saw in verse 113, namely, hatred of what is wrong contrasted with a love of what is good. As these verses put it, 

Because I love your commands more than gold, more than pure gold,

and because I consider all your precepts right, I hate every wrong path. 

In the last of these three stanzas (ayin, vv. 121-128), which have to do with walking by God's Word, the contrasts that have already been introduced reoccur: the need for clear direction in a sinful, dark world; threat of enemies versus the sustaining grace of God; and hatred of sin versus love of God's Word. But going on from the writer's awe of God introduced at the end of the last stanza, what this stanza emphasizes is that if we are to walk as God wants us to walk, we must keep looking to him intently and at all times. As far as sin is concerned, we must look to God's commandments. As far as dangers go, we must look to God for deliverance.
