"The Lord is my Shepherd, I lack nothing."-Psalm 23:1
Explanation
Explanation from https://www.studylight.org/commentary/psalms/23-1.html
"God condescends to call himself the Shepherd of his people, and his followers are considered as a flock under his guidance and direction."
"He leads them out and in, so that they find pasture and safety.
He knows where to feed them, and in the course of his grace and providence leads them in the way in which they should go.
He watches over them and keeps them from being destroyed by ravenous beasts.
If any have strayed, he brings them back.
He brings them to the shade in times of scorching heat; in times of persecution and affliction, he finds out an asylum for them.
He takes care that they shall lack no manner of thing that is good.""Jesus Christ is the good Shepherd; the Shepherd who, to save his flock, laid down his own life."
"I shall not want" - How can they? He who is their Shepherd has all power in heaven and earth; therefore he can protect them. The silver and gold are his, and the cattle on a thousand hills; and therefore he can sustain them. He has all that they need, and his heart is full of love to mankind; and therefore he will withhold from them no manner of thing that is good."
