YODH or HAND, is the focus of this section of Psalm 119. It first and foremost focuses our gaze on the creator. His hands have made us (vs 73). Additionally, there are two words that are repeated throughout the Psalm, which are: good and let.

God is good. No matter what we face.

God in in control. No matter what we face.

It is for our good that we go through affliction, it shows us HE is good, and He is in control of all.
