Verse 31. - As Moses the servant of the Lord commanded (see Exodus 20:25; Deuteronomy 27:4, 5). Here, and in ver. 33, we find the writer making an extract from the Book of Deuteronomy. As has been before said, the natural explanation is that the Book of Joshua was written after the Book of Deuteronomy, and that the Book of Deuteronomy was written by Moses, or how could Joshua have carried out instructions which had never been given? The Elohist, Jehovist, and Denteronomist theory supposes the compiler of the Book of Joshua to have done his work in so perfunctory a fashion, that it is quite possible for critics living at a distance of three thousand years and more to detect the various fragments of which his mosaic is constructed. He is so void of common sense as to have inserted this narrative in a place so obviously unsuitable that it involves a palpable contradiction to probability and common sense, and this when he could have placed it in a dozen other parts of the book where no such improbability would be involved. Yet, in spite of the incredible carelessness with which he put his materials together, we are required to believe that "the Deuteronomist" had the foresight to insert the fulfilment of the command of Moses which he had invented in Deuteronomy 11:26-30; Deuteronomy 27:1-26; and that in so doing he abbreviated the narrative so as to leave out many details of his own invention. Now, under the supposition of a later fabrication of supplementary observances to be imposed upon the children of Israel, it is hardly probable that the account of the plaster with which the stones were to be plastered, and the enumeration of the tribes and the curses, would be omitted, since by the hypothesis the object of the Deuteronomist was to secure implicit obedience to the sacerdotal enactments he was inventing. But on the hypothesis of the genuineness of both writings everything fits in naturally enough. An altar of whole stones, over which no man hath lift up any iron. As though to intimate (see Exodus 20:25) that all should be natural and spontaneous in the worship of God, and that as little of human devising should be introduced as possible. The altar must be raised by man, but the principles of the worship must not be devised by him. This interpretation, however, is rejected by Calvin, who thinks that all that was meant was to preclude the perpetual existence of the altar (though how the substitution of whole for hewn stones could effect this is not apparent); and Keil and Bahr ('Symbolik,' 1. pp. 487, 488),who think that the altar ought (Exodus 20:24) properly to be of earth, since sacrifice is rendered necessary by man's earthly or carnal nature, and that unhewn stone is the only substitute for earth which is allowed. But surely man's handiwork is the offspring of his unregenerate nature, and therefore may, from this point of view, be rightly employed in sacrifice. Hengstenberg ('Gesehichte des Reiches Gottes,' p. 223) thinks that the reason of the command was that, since only one place of worship was permitted for all Israel, an altar had sometimes to be hastily thrown up. But when we consider the symbolic character of the Mosaic worship, we are compelled to reject this interpretation as unsatisfactory. Benjamin of Tudela (see Drusius in loc.) appears to have supposed that these stones were those which had been taken out of Jordan. Masius devotes considerable space to the refutation of this opinion (see also note on last verse). And they offered thereon. Delitzsch remarks on the inversion of the order here, as compared with Deuteronomy 27. But this is obviously the true order. The worship would naturally precede the ceremony rather than follow it.
8:30-35 As soon as Joshua got to the mountains Ebal and Gerizim, without delay, and without caring for the unsettled state of Israel, or their enemies, he confirmed the covenant of the Lord with his people, as appointed, De 11; 27. We must not think to defer covenanting with God till we are settled in the world; nor must any business put us from minding and pursuing the one thing needful. The way to prosper is to begin with God, Mt 6:33. They built an altar, and offered sacrifice to God, in token of their dedicating themselves to God, as living sacrifices to his honour, in and by a Mediator. By Christ's sacrifice of himself for us, we have peace with God. It is a great mercy to any people to have the law of God in writing, and it is fit that the written law should be in a known tongue, that it may be seen and read of all men.
and they offered thereon burnt offerings unto the Lord, and sacrificed peace offerings; by way of thanksgiving for the good land they were introduced into, and this was what they were ordered to do by Moses, Deuteronomy 27:6.
