A Master Mason, in teaching apprentices, makes use of the compasses and the square. Ye who are engaged in the pursuit of wisdom must also make use of the compass and square.[21]

There are even evidences, in the earliest historic records of China, of the existence of a system of faith expressed in allegoric form, and illustrated by the symbols of building. The secrets of this faith seem to have been orally transmitted, the leaders alone pretending to have full knowledge of them. Oddly enough, it seems to have gathered about a symbolical temple put up in the desert, that the various officers of the faith were distinguished by symbolic jewels, and that at its rites they wore leather aprons.[22] From such records as we have it is not possible to say whether the builders themselves used their tools as emblems, or whether it was the thinkers who first used them to teach moral truths. In any case, they were understood; and the point here is that, thus early, the tools of the builder were teachers of wise and good and beautiful truth. Indeed, we need not go outside the Bible to find both the materials and working tools of the Mason so employed:[23]

For every house is builded by some man; but the builder of all things is God ... whose house we are.[24]

Behold, I lay in Zion for a foundation a tried stone, a precious corner-stone, a sure foundation.[25]

The stone which the builders rejected is become the head of the corner.[26]

Ye also, as living stones, are built up into a spiritual house.[27]

When he established the heavens I was there, when he set the compass upon the face of the deep, when he marked out the foundations of the earth: then was I by him as a master workman.[28]

The Lord stood upon a wall made by a plumbline, with a plumbline in his hand. And the Lord said unto me, Amos, what seest thou? And I said, A plumbline. Then said the Lord, Behold, I will set a plumbline in the midst of my people Israel: I will not again pass by them any more.[29]

Ye shall offer the holy oblation foursquare, with the possession of the city.[30]

And the city lieth foursquare, and the length is as large as the breadth.[31]
