Imagine living in an arid land. Little rain. Little vegetation. Imagine what a tree would signify.
This first psalm, the opening of this wisdom book, has at its center the image of trees. Fruitful--their leaves do not wither, in all they do they prosper.
A tree in an arid land can prosper only if it is planted near a water source.
The teaching of the Lord provides what is necessary for us to grow, to prosper, to bear fruit. Ignoring that teaching is what the wicked do, the ones who become like chaff, driven by the wind.
Look back at Leviticus 19:1-2, 15-18.
