In enumerations where the prophets exhaust everything pertaining to sacred gifts and liturgic performances, in which, for the sake of lengthening the catalogue, they do not shrink from repetitions even, there is not any mention of incense-offerings, neither in Amos (iv. 4 seq., v. 21 seq.) nor in Isaiah (i. 11 seq.) nor in Micah (vi. 6 seq.). Shall we suppose that they all of them forget this subject by mere accident, or that they conspired to ignore it? If it had really existed, and been of so great consequence, surely one of them at least would not have failed to speak of it. The Jehovistic section of the Hexateuch is equally silent, so also the historical books, except Chronicles, and so the rest of the prophets, down to Jeremiah, who (vi.20) selects incense as the example of a rare and far-fetched offering: "To what purpose cometh there to me incense from Sheba, and the precious cane from a far country?" Thenceforward it is mentioned in Ezekiel, in Isaiah (xl.-lxvi.), in Nehemiah, and in Chronicles; the references are continuous. The introduction of incense is a natural result of increased luxury; one is tempted to conjecture that its use must have first crept into the Jehovah worship as an innovation from a more luxuriously-developed foreign cultus. But the importance which it has attained in the ritual legislation of the Pentateuch is manifest above all from this, that it has led to the invention of a peculiar new and highly sacred piece of furniture, namely, the golden altar in the inner tabernacle, which is unknown to history, and which is foreign even to the kernel of the Priestly Code itself. We expect to find the altar of incense in Exodus xxv.-xxix., but find it instead as an appendix at the beginning of Exodus xxx. Why not until now? why thus separated from the other furnishings of the inner sanctuary? and not only so, but even after the ordinances relating to the adornment of the priests, and the inauguration of the divine service? The reason why the author of chaps. xxv.-xxix. is thus silent about the altar of incense in the passage in which the furniture of the tabernacle, consisting of ark, table, and candlestick, is described, is, that he does not know of it. There is no other possibility; for he cannot have forgotten it. /1/
