a Bible passage
15That which is, already has been; that which is to be, already is; and God seeks out what has gone by.
requireth that … past—After many changes, God's law requires the return of the same cycle of events, as in the past, literally, "that which is driven on." The Septuagint and Syriac translate: "God requireth (that is, avengeth) the persecuted man"; a transition to Ec 3:16, 17. The parallel clauses of the verse support English Version.
