Psalm 23 – Vatican.va
Dear Brothers and Sisters,
Turning to the Lord in prayer implies a radical act of trust, in the awareness that one is entrusting oneself to God who is good, “merciful and gracious, slow to anger, and abounding in steadfast love and faithfulness” (Ex 34:6-7; Ps 86[85]:15; cf. Joel 2:13; Jon 4:2; Ps 103 [102]:8; 145[144]:8; Neh 9:17). For this reason I would like to reflect with you today on a Psalm that is totally imbued with trust, in which the Psalmist expresses his serene certainty that he is guided and protected, safe from every danger, because the Lord is his Shepherd. It is Psalm 23 [22, according to the Greco-Latin numbering], a text familiar to all and loved by all.
“The Lord is my shepherd, I shall not want”: the beautiful prayer begins with these words, evoking the nomadic environment of sheep-farming and the experience of familiarity between the shepherd and the sheep that make up his little flock. The image calls to mind an atmosphere of trust, intimacy and tenderness: the shepherd knows each one of his sheep and calls them by name; and they follow him because they recognize him and trust in him (cf. Jn 10:2-4).
He tends them, looks after them as precious possessions, ready to defend them, to guarantee their well-being and enable them to live a peaceful life. They can lack nothing as long as the shepherd is with them. The Psalmist refers to this experience by calling God his shepherd and letting God lead him to safe pastures: “He makes me lie down in green pastures. He leads me beside still waters; he restores my soul. He leads me in paths of righteousness for his name’s sake” (Ps 23[22]:2-3).
The vision that unfolds before our eyes is that of green pastures and springs of clear water, oases of peace to which the shepherd leads his flock, symbols of the places of life towards which the Lord leads the Psalmist, who feels like the sheep lying on the grass beside a stream, resting rather than in a state of tension or alarm, peaceful and trusting, because it is a safe place, the water is fresh and the shepherd is watching over them.
And let us not forget here that the scene elicited by the Psalm is set in a land that is largely desert, on which the scorching sun beats down, where the Middle-Eastern semi-nomad shepherd lives with his flock in the parched steppes that surround the villages. Nevertheless the shepherd knows where to find grass and fresh water, essential to life, he can lead the way to oases in which the soul is “restored” and where it is possible to recover strength and new energy to start out afresh on the journey.
As the Psalmist says, God guides him to “green pastures” and “still waters”, where everything is superabundant, everything is given in plenty. If the Lord is the Shepherd, even in the desert, a desolate place of death, the certainty of a radical presence of life is not absent, so that he is able to say “I shall not want”. Indeed, the shepherd has at heart the good of his flock, he adapts his own pace and needs to those of his sheep, he walks and lives with them, leading them on paths “of righteousness”, that is, suitable for them, paying attention to their needs and not to his own. The safety of his sheep is a priority for him and he complies with this in leading his flock.
Dear brothers and sisters, if we follow the “Good Shepherd” — no matter how difficult, tortuous or long the pathways of our life may seem, even through spiritual deserts without water and under the scorching sun of rationalism — with the guidance of Christ the Good Shepherd, we too, like the Psalmist, may be sure that we are walking on “paths of righteousness” and that the Lord is leading us, is ever close to us and that we “shall lack nothing”. For this reason the Psalmist can declare his calm assurance without doubt or fear: “Even though I walk through the valley of the shadow of death, I fear no evil; for you are with me; your rod and your staff they comfort me” (v. 4).
