In Psalm 1, the man who delights in the law of the LORD is like what?

Answer: A tree planted by water

He is like a tree planted by streams of water (KJV: rivers), yielding fruit in season, but the wicked are like chaff driven by the wind.

“But his delight is in the Law of the LORD, and on His law he meditates day and night. He is like a tree planted by streams of water, yielding its fruit in season, whose leaf does not wither, and who prospers in all he does. Not so the wicked! For they are like chaff driven off by the wind.”— Psalm 1:2-4 (BSB)
