CLAIM: This is a prayer describing the fullness of Jesus’ reign over the earth that provides abundant provision for all, and fills the nations with His glory. This is also an actual prayer for Solomon as king of Israel, the successor to the throne, during David’s last days. The scope and fullness of this will only be expressed during the reign of Jesus as the greater David.
The direct application was Solomon, however the implications are obviously pointing to Jesus. Various aspects would apply to Jesus and be fully fulfilled, and certain aspects, depending on interpretation could yet be future. Psalms by their nature are different than the regular prophets in form, so direct correlation is not always immediate. These could bee seen as events that related to his being seated in the heavens in Ephesians 1:19-20, or could specify a yet future time.
