9395. 'And half of the blood he sprinkled over the altar' means Divine Truth from the Lord's Divine Human. This is clear from the meaning of 'the blood' as Divine Truth, dealt with just above in 9393; and from the meaning of 'the altar' as a representative of the Lord's Divine Human, dealt with in 921, 2777, 2811, 4489, consequently the chief representative of worship of the Lord, 4541, 8935, 8940. The reason why this 'half of the blood', which was sprinkled over the altar, means Divine Truth emanating from the Lord's Divine Human and the other 'half of the blood', which was sprinkled over the people, verse 8 below, means this Divine Truth when accepted by a member of the Church, is this: A covenant was being established, and by 'a covenant' is meant being joined together, 665, 666, 1023, 1038, 1864, 1996, 2003, 2021, 6804, 8767, 8778, and the Lord comes to be joined to a member of the Church when Divine Truth which emanates from the Lord is accepted by a person. From this it is evident why blood was used, and when sprinkled over the altar and over the people was called the blood of the covenant, verse 8.

2811. 'And Abraham built the altar there' means preparation of the Lord's Divine human. This is clear from the meaning of 'the altar' and of 'building the altar'. Altars used to mean all worship in general because they were the chief feature of the worship of the representative Church, 921. And because they meant all worship in general they meant the Lord's Divine Human, for the Lord's Divine Human is essentially present in all worship and all doctrine, so much so that it is the very essence of worship itself and doctrine itself. This becomes clear also from the Holy Supper which superseded altars, that is, burnt offerings and sacrifices, 2165, 2187, 2343, 2359. The Holy Supper is the chief feature of external worship because it is the Lord's Divine Human that is bestowed there. From all this it may become clear, and so without further explanation, that 'building an altar' means preparing the Divine human. The final preparation of the Lord's Divine human for undergoing the last degrees of temptation is the subject in the present verse and is described by the statement that Abraham laid the pieces of wood in order, bound Isaac his son, and laid him on the altar, upon the pieces of wood.
