God is my shepherd and I will never want it.
Describing the Lord as a shepherd and his people as sheep is a common expression in the Bible. The earliest description of the image of God is in Genesis 48: 15, which translates as "the God who has shepherd me all my life until today" and literally translates as "my shepherd". In order to understand and appreciate the wonderful meaning of this imagination, we must understand the harsh environment of the Jewish wilderness and the close relationship between shepherds and sheep, especially the love generated by their long-term loneliness.
In the Bible, the shepherd refers to the rabbi, that is, the teacher who shepherds Israel. Israel is like a flock of sheep. Teachers look at them like children, just like shepherds.
Now the meaning of shepherd has not changed, that is, shepherd, which means a priest in a narrow sense and a preacher in a broad sense. Believers belong to watered sheep, and shepherds are a group of people who pass on God's knowledge.
