4401. And he erected there an altar. That this signifies interior worship, is evident from the signification of “erecting an altar,” as being worship. For an altar was the principal representative of the Lord (see n. 921, 2777, 2811), and hence also the principal thing in worship. By worship is here meant interior worship from the Divine Spiritual, which subject now follows.

2811. And Abraham built there the altar. That this signifies the preparation of the Lord’s Human Divine, is evident from the signification of an “altar,” and of “building an altar.” “Altars” signified all worship in general, because they were the primary things of the worship of the representative church (n. 921); and as they signified all worship in general, they signified the Lord’s Divine Human, for the Lord’s Divine Human is all worship and all doctrine; so much so as to be worship itself and doctrine itself; as may be seen also from the Holy Supper, which succeeded to altars, or to burnt-offerings and sacrifices (n. 2165, 2187, 2343, 2359), and which is the primary thing of external worship, because it is the Lord’s Divine Human which is there given. That to “build an altar” is to prepare the Human Divine, is evident from the above, and thus without explication. The final preparation of the Lord’s Human Divine for undergoing the last degrees of temptation is treated of in this verse, and is described by Abraham laying the wood in order, binding Isaac his son, and placing him on the altar upon the wood.
