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.
This Book of the Law must not depart from your mouth; meditate on it day and night, so that you may be careful to do everything written in it. For then you will prosper and succeed in all you do.
Significance
Psalm 1:2-3 and Joshua 1:8 share the distinctive phrase "meditate day and night" (יֶהְגֶּה יוֹמָם וָלַיְלָה, yehgeh yomam valayelah) on God's Torah, both connecting this meditation to prospering (הִצְלִיחַ, hitsliach) in all one does. Joshua 1:8 commands: "This Book of the Law shall not depart from your mouth; you shall meditate on it day and night... then you will make your way prosperous." Psalm 1:2-3 echoes this nearly verbatim: "on His law he meditates day and night... who prospers in all he does." The Psalm universalizes what was originally a specific charge to Joshua as military-covenant leader, transforming it into the gateway beatitude for the entire Psalter, making Torah meditation the foundation of the blessed life for every Israelite. The shared verb הָגָה (hagah) denotes a low, vocal murmuring rather than silent reflection, so both texts picture Torah devotion as the continual, audible rehearsal of God's word.
