It should also be remembered that Old Testament revelation, although it is true revelation, that is to say of universal validity, nevertheless represents a historical quantity; that is to say, it is adapted to the understanding of its day and to the confessional standards and confessional forms then prevailing. For the child, two times two equals four is the beginning and end of arithmetic. The mathematician sees far beyond that, but two times two is four for him also with the same unconditional validity as for the child. — Köhler, L. 1957. Old Testament Theology (translated by A.S. Todd). Philadelphia: The Westminster Press, 64.
Many students of the Bible would do well to remember this. Others have pointed this out in their own way in more recent times, but it was neat to read this from such an early era in OT theological studies.
