building material material used in the construction of buildings It is also possible to understand ἐνδώμησις in the sense of ‘foundation’ (see ἐνδώμησις[b], 7.41).
7.41 · Constructions · Parts and Areas of Buildings
foundation that on which a structure is built In some languages it is possible to describe a typical foundation in ancient times as ‘large stones underneath the walls.’ In other languages, however, this may seem to be quite a meaningless type of expression, since foundations are only made secure by driving stakes deep into the ground. Therefore, it may be best to describe the function of a foundation by ‘what keeps the walls firm’ or ‘how the walls are made not to move’ or ‘what goes beneath the walls.’
A number of scholars, however, prefer to understand ἐνδώμησις in the context of REV 21:18 as the material of which the wall was made, rather than as the foundation of the wall (see ἐνδώμησις[a], 7.77).
