10027. 'And put it on the horns of the altar with your finger' means power that is Divine and the Lord's, originating in Himself. This is clear from the meaning of 'the horns of the altar' as the power of truth that springs from good (for the meaning of 'horns' as power, see 9081, 9719-9721, and for the meaning of 'the altar' as that which was representative of the Lord in respect of Divine Good, or that which was representative of Divine Good within the Lord, 9388, 9389, 9714, 9964); and from the meaning of 'finger' as power, dealt with in 7430. His acting by the power that was His own, that is, the power originating in Himself is meant because Moses was the one who applied the blood, and he represents the Lord in respect of Divine Truth, 9372, 9806; this is why the words 'with your finger' are used. The reason why the blood was to be put first on the horns of the altar was in order that the actual power of Divine Truth springing from Divine Good might be represented; for by the power of Divine Truth springing from Divine Good all things were done or made, and nothing without it, see the places referred to above in 10019.

9388. 'And built an altar under the mountain' means a representative sign of the Lord's Divine Human in respect of Divine Good from Him. This is clear from the meaning of 'an altar' as a representative sign of the Lord's Divine Human, dealt with in 921, 2777, 2811, 4489, and therefore the chief representative of worship of the Lord, 4541, 8935, 8940; and from the meaning of 'the mountain' as the good of love, dealt with in 4210, 6435, 8327, 8658, 8758, in this instance the Divine Good of love which emanates from the Lord, since it was Mount Sinai, where the Lord was then. 'Mount Sinai' means Divine Good united to Divine Truth emanating from the Lord, see 8805.
