Salmos 23:1
Having said in the psalm before this, "The needy eat and will be filled, and those who seek him out will praise the Lord," and again, "All the prosperous of the earth ate and adored him," here he suggests the provider of such food and calls the feeder shepherd. This in fact is the name Christ the Lord also gave himself: "I am the good shepherd, I know my own, and I am known by my own." It is also what he called himself through the prophet Ezekiel. So here, too, all who enjoyed the saving food cry out, "The Lord shepherds me, and nothing will be wanting for me": this shepherd regales those shepherded by him with enjoyment of good things of all kinds. — COMMENTARY ON THE PSALMS 23:1
Salmos 23:2
He hints at the water of rebirth, in which the baptized person longs for grace and sheds the old age of sin and is made young instead of being old. — COMMENTARY ON THE PSALMS 23:2
Salmos 23:4
"Your rod and your staff comforted me": with one he supports my weakness, with the other he guides toward the right way. You would not be wrong, however, to apply this to the saving cross: by its seal and remembrance we are rid of the hostile demons and guided to the true path. This is the meaning of "your rod and your staff comforted me": the cross is assembled from two rods, with the upright staff confirming and directing those who believe in him and strengthening those who are weak, and using the crossbar as a rod against the demons. — COMMENTARY ON THE PSALMS 23:3
Salmos 23:6
Providing these good things is your ineffable lovingkindness, not awaiting our request but closely following us like fugitives, anticipating our needs, giving us a share in salvation, providing residence in the divine dwellings, one in the present life, one in the future. — COMMENTARY ON THE PSALMS 23:4
