10123. 'And you shall cleanse from sin on the altar' means purification from evils in heaven and in the Church. This is clear from the meaning of 'cleansing' as purifying; from the meaning of 'sin' as evil, for all evil that a person is guilty of is called sin; and from the meaning of 'the altar' as that which is representative of the Lord in regard to Divine Good and of the worship of Him, dealt with in 9714, 9964, at this point in respect of Divine Good in heaven and in the Church. The subject is still the Lord's influx, presence, and reception there, and for this reason 'the altar' also means heaven and the Church in respect of reception of Divine Good from the Lord there. For that which is Divine and the Lord's is what makes heaven and the Church; this is so because the Lord dwells there in what is His and not in what is a person's own. This too explains why 'the altar' also means the actual person in whom heaven is present or in whom the Church is present, and so in whom the Lord is present; and in the abstract sense, in which no actual person is envisaged, 'the altar' means the Good itself which comes from the Lord and is present with the angels of heaven and with members of the Church.

[2] The word 'altar' is used with these meanings in John,

I was given a reed like a rod, and the angel stood and said to me, Measure the temple of God, and the altar, and those who worship in it. Revelation 11:1.

Here 'the temple of God, and the altar' are heaven and the Church, 'the temple' being the spiritual Church and 'the altar' the celestial Church. 'Measuring' means recognizing the amount and the essential nature of truth and good; and this is why it says not only 'Measure the temple, and the altar' but also 'those who worship in it'. For the meaning of 'the temple' as the spiritual Church, see 3720; and for that of 'measuring' as recognizing the state of affairs as regards truth and good, 9603. In the same book,

I heard another angel from the altar saying, O Lord God Almighty, true and righteous are Your judgements. Revelation 16:7.

'From the altar' means from the inmost heaven, where celestial good reigns, celestial good being the good of love to the Lord. In Jeremiah,

The Lord has abandoned His altar, He has abominated His sanctuary. Lamentations 2:7.

'Abandoning the altar and the sanctuary' refers to everything of the Church, 'the altar' being everything of the Church as regards good, and 'the sanctuary' everything of the Church as regards truth.

8680. 'And Jethro, the father-in-law of Moses, took a burnt offering and sacrifices for God' means worship springing from the good of love and the truths of faith. This is clear from the meaning of 'a burnt offering and sacrifices' as representatives of celestial and spiritual realities that belong to internal worship, 'burnt offerings' being representative of celestial realities, that is, aspects of the good of love, and 'sacrifices' being representative of spiritual ones, that is, aspects of the truth of faith, dealt with in 922, 923, 1823, 2180, 2805, 2807, 2830, 3218, 3519, 6905. The representation of 'burnt offerings' as aspects of the good of love, and of 'sacrifices' as aspects of the truth of faith, is clear from their institution - from the requirement that in burnt offerings everything was to be burnt, both the flesh and the blood, but that in sacrifices the flesh was to be eaten, as may be seen in chapters 1-5 of Leviticus; Numbers 28; and in Deuteronomy, where the following words occur,

You are to present, your burnt offerings, the flesh and the blood, on the altar of Jehovah your God; the blood of the sacrifices shall be poured out on the altar of Jehovah your God, and the flesh you shall eat. Deuteronomy 12:27.

The reason why those two realities were represented by the burnt offerings and sacrifices is that burnt offerings and sacrifices represented all worship of God in general, 923, 6905; and worship of God in general is founded on love and faith. Without these it is not worship, only ritual such as is performed by the external man who has no internal and so no life within him.
