1 Blessed is the man
who walks not in the counsel of the wicked,
nor stands in the way of sinners,
nor sits in the seat of scoffers;
2 but his delight is in the law of the Lord,
and on his law he meditates day and night.
3 He is like a tree
planted by streams of water
that yields its fruit in its season,
and its leaf does not wither.
In all that he does, he prospers.
4 The wicked are not so,
but are like chaff that the wind drives away.
5 Therefore the wicked will not stand in the judgment,
nor sinners in the congregation of the righteous;
6 for the Lord knows the way of the righteous,
but the way of the wicked will perish.
From Charles Spurgeon on Psalm 1:
Title.—This Psalm may be regarded as The Preface Psalm, having in it a notification of the contents of the entire Book. It is the psalmist’s desire to teach us the way to blessedness, and to warn us of the sure destruction of sinners. This then, is the matter of the first Psalm, which may be looked upon, in some respects, as the text upon which the whole of the Psalms make up a divine sermon.
Division.—This Psalm consists of two parts: in the first (from verse 1 to the end of the 3rd) David sets out wherein the felicity and blessedness of a godly man consisteth, what his exercises are, and what blessings he shall receive from the Lord. In the second part (from verse 4 to the end) he contrasts the state and character of the ungodly, reveals the future, and describes, in telling language, his ultimate doom.
