Jesus spoke about Himself as the Good Shepherd in John 10:11-18.
The Lord is my shepherd. I lack nothing. 2 He causes me to lie down in green pastures.
He leads me beside quiet waters. (Ps 23:1-2 EHV)
I am the good shepherd. The good shepherd gives His life for the sheep. (Joh 10:11 NKJV)
But seek first his kingdom and his righteousness, and all these things will be given to you as well. (Mt 6:33 NIV)
And my God will supply all your needs according to His riches in glory in Christ Jesus. (Phil 4:19 NASB)
And when the chief Shepherd appears, you will receive the unfading crown of glory. (1 Pet 5:4 ESV)
A shepherd is an overseer of his flock. By identifying Himself as the Good Shepherd, Jesus was claiming to be the Messiah foretold in the Scriptures.
In Ezekiel 34:1-10, the Lord outlines what constitutes a bad shepherd. Through Ezekiel 34:11-31, Jesus establishes Himself as the Savior and Messiah, and the new leader of the Israelites. He is the Good Shepherd who protects, provides for and cares for His sheep. We are the sheep of His pasture!
Jesus calls out to all people to (obey) His voice. Glory to God!
