What does the Bible say about the Lord being my shepherd?

Psalm 23 depicts the Lord as a shepherd who ensures that His flock lacks nothing. The imagery highlights His provision, guidance, and care, as He makes the sheep lie down in green pastures and leads them beside still waters. This passage emphasizes a personal relationship between the believer and the Lord, where David declares, 'the Lord is my shepherd.' It suggests an intimate assurance that He will provide for all needs, both spiritually and physically, throughout the believer's life.
