Hear my prayer, O Lord
The references of (Psa 102:25-27) to Christ (Heb 1:10-12) assures us that in the preceding verses of Psalm 102 we have, prophetically, the exercises of His holy soul in the days of His humiliation and rejection.
See Psalm 110 (Psa 110:1-7), next in order of the Messianic Psalms.
That is, nations.
(See Scofield) - (Psa 19:9).
