He will be like a tree firmly planted by streams of water,The blessed man is compared to a tree. Trees are of the strongest and mightiest objects which dwell on planet earth. When fully grown, a tree towers over most of the earthly creation. Good trees possess great sturdiness, they are unmovable, and hard to uproot; they are a creative beauty — a testimony to God's great handiwork at creation.
Which yields its fruit in its season
And its leaf does not wither;
And in whatever he does, he prospers. (Psalm 1:3)
The blessed man who both despises the counsel of the wicked and continually meditates in the law of the LORD is said to be like a tree planted by streams of water. This is no ordinary tree — it is nourished with a constant supply of water; it bears fruit at the appropriate time and its leaf does not wither.
Whatever the blessed man does, he prospers. This does not refer merely to temporal earthly wealth; rather, it refers to eternal prosperity. Such a man stands in stark contradiction to the cursed man — who is like a tree that feeds upon poison — a poison which at first seems to be beneficial, but has an end result of eternal death.
