Psalm 1

Two ways of life, set side by side: the person rooted in God's instruction, like a tree by water, and the wicked, like chaff the wind takes. The blessing isn't in avoiding bad company for its own sake, but in delight. The person loves God's law and turns it over day and night. Growth here is slow and seasonal ("fruit in season"), not instant.

"But his delight is in the Law of the LORD, and on His law he meditates day and night." (Psalm 1:2)

Versions/Hebrew: In 1:6 the BSB says the LORD "guards" the path of the righteous, but the Hebrew verb is yada [3045], "knows" (WEB, KJV, YLT all say "knows"). God's care is personal knowing. "Meditates" is hagah [1897], to murmur or mutter, reading half aloud to yourself.
