1. The Lord is my Shepherd; I shall not want.
"Only a shepherd could write Psalm 23, and David was a shepherd. 
The Lord is the Shepherd of His people and they are His sheep.
The Lord is the Shepherd of His people and they are His sheep.
Jesus said, as we read in John 10:27, “My sheep hear My voice, and I know them, and they follow Me.”—we did not belong to God's flock, but through the death of His Lamb, we
are clothed in the robe of His righteousness and are able to enter the
true fold.
.... the various regions through which He leads them are described in order.
---And they are three: rest, work, and sorrow.
Rest, strange to say, in the
past;
work in the present;
and sorrow, the valley of the shadow, still
to come...." BibleInfo
