1 Blessed is the child that walked not in the counsel of the wicked, Nor in the way of sinners, Nor sat in the seat of scoffers;
2 But in the law of the Lord is his delight, And in his law day and night.
3 It will be like a tree planted by the streams of water, and its leaf does not fall;
And whatever he does shall prosper.
4 Not so bad,
That they are like the time that the wind snatches.
5 Therefore, the wicked will not rise at the judgment,
Not sinners in the congregation of the righteous.
6 For Jehovah knows the way of the righteous;
But the path of the wicked will perish.
Psalms 1 Reina-Valera 1960 (RVR1960)
In these statements of David is the essence of the promise given to those who read these poems and meditate on them, he affirms that they will be blessed because it is what God has promised and certainly the friends we choose significantly influence the future and success of our lives
