8940. 'And if you make for Me an altar of stones' means a representative kind of worship in general that is composed of truths. This is clear from the meaning of 'an altar' as a representative of Divine worship in general, dealt with in 921, 2777, 2811, 4489; and from the meaning of 'stones' as truths, dealt with in 643, 1298, 3720, 3769, 3771, 3773, 3789, 3798, 6426, 8609. There is worship of the Lord that springs from good, and there is worship of Him that springs from truth. Worship of the Lord springing from good was represented by an altar of soil, and worship springing from truth by an altar of stone. Regarding the first and the second kinds of worship, see above in 8935. It was because an altar of stone was a sign of worship springing from truth that they were commanded to set up such an altar as soon as they crossed the Jordan and came into the land of Canaan, and to write on it the Commandments contained in the Law, that is, God's truths from heaven. For by the Ten Commandments are meant all God's truths in summary form. That altar is spoken of in Moses as follows,

When you cross the Jordan you shall set up for yourself large stones, and coat them with lime. Then you shall write on them all the words of the Law. Afterwards, you shall build there an altar to Jehovah your God, an altar of stones, which you shall not hew with any iron tool. ¹ With whole stones you shall build the altar of Jehovah your God, and present ² on it burnt offerings and eucharistic offerings. And you shall write on the stones of the altar the words of the Law, expressing them very plainly. Deuteronomy 27:1-8; Joshua 8:30-32.

[2] The reason why they were to write the words of the Law on stones of the altar was that truths were meant by 'stones', and worship that springs from truths by 'an altar of stones'. This was also the reason why the Ten Commandments, which were a sign of Divine Truths in their entirety, were inscribed on tablets of stone. The reason why it had to be done as soon as they crossed the Jordan was that the Jordan, which was the first and outermost boundary of the land of Canaan on the side where the wilderness lay, meant introduction into the Church or heaven, which is accomplished through cognitions or knowledge of truth and good, thus through truths from the Word, 4255. For all the rivers serving as boundaries of that land meant the first and outermost reaches of the Lord's kingdom, 4116, 4240. By 'the stones of the altar' the truths of faith are also meant in Isaiah,

He will remove sin when He makes all the stones of the altar like chalk-stones scattered about. Isaiah 27:9

This refers to the ruination of the Church. 'The stones of the altar like chalk-stones scattered about' stands for the truths of faith that inspire worship after something similar has happened to them. As regards altars in general, they were made out of soil, stones, bronze, wood, and also gold - out of bronze, wood, and gold because these materials served to mean good. For an altar of bronze, see Ezekiel 9:2; for an altar of wood, Ezekiel 41:22; and for an altar of gold, which was the altar of incense, 1 Kings 6:22; 7:48; Revelation 8:3. That 'bronze' means good, see 425, 1551; that 'wood' does so, 643, 2784, 2812, 3720, 8354; and that 'gold' does so as well, 113, 1551, 1552, 5658.

Voetnoten:

8935. 'An altar of soil you shall make for Me' means something which in a general way represents worship that springs from good. This is clear from the meaning of 'an altar' as the chief representative of the Lord and consequently of the worship of Him, dealt with in 921, 2777, 2811, 4489, 4541; and from the meaning of 'soil' or 'the ground' as good. The reason why 'the ground' stands for good is that a Church which abides in good is meant by 'the ground', 566. This is why Adam was said to be formed from the ground, at Genesis 2:7; 3:19; for one who belonged to the celestial Church, that is, the Church itself abiding in good, was meant by him, 478, 479. Since there are two entities that inspire worship of the Lord - goodness and truth - worship springing from good was represented by an altar of soil, while worship springing from truth was represented by an altar of stones. Both kinds of altars are the subject here; and those two entities that inspire worship are called faith and charity. Worship springing from truth has connection with faith, and worship springing from good has connection with charity.

[2] As regards worship inspired by faith and worship inspired by charity, or that which springs from truth and that which springs from good, the situation is that before a person has been regenerated his worship consists of truth, but after he has been regenerated it consists of good. Before a person has been regenerated he is led by means of truth to good, that is, by means of faith to charity; but when he has been regenerated he abides in good and consequently in truth, that is, in charity and consequently in faith, 8516, 8539, 8643, 8648, 8658. These two kinds of worship are what the altars of soil and of stone represent. The reason why the altar is the chief representative of worship of the Lord is that burnt offerings and sacrifices were offered on it; and it was in these that the worship of God by the Hebrew nation, and subsequently by the Israelite and Jewish nation, chiefly consisted, 923, 1343, 2180, 2805, 2807, 2830, 3519, 6405.
