+Psalm 1The Two Ways
+
+1. How happy is the one who does not
+walk in the advice of the wicked
+or stand in the pathway with sinners
+or sit in the company of mockers!
+
+2. Instead, his delight is in the Lord's instruction,
+and he meditates on it day and night.
+
+3. He is like a tree planted beside flowing streams
+that bears its fruit in its season,
+and its leaf does not wither.
+Whatever he does prospers.
+
+4. The wicked are not like this;
+instead, they are like chaff that the wind blows away.
+
+5. Therefore the wicked will not stand up in the judgment,
+nor sinners in the assembly of the righteous.
+
+6. For the Lord watches over the way of the righteous,
+but the way of the wicked leads to ruin.
