This idea is present throughout Ps22. O my Strength, come quickly to help me . The partitioning of Palestine into TWO, east and west of Jordan River, was a process of dividing and separating. This process is abundantly illustrated in Ps22. This is another example of separation.
Life begets life.
Just as an amoeba is split into two, the birth of a child is a separation of life from life. In Christ, there is neither Jew nor Gentile. All Christians must be born again or we cannot enter the Kingdom of God. 6 Flesh gives birth to flesh, but the Spirit gives birth to spirit. The wind blows wherever it pleases.
