(15-22) With regard to the two pillars, Jachin (“He shall establish”) and Boaz (“In it is strength”), the text gives no account of their destination, except that they were set up in the porch of the Temple (1Kings 7:21). Mr. Fergusson considers that they were supports to the roof of the vestibule; and if this were thirty cubits high, the twenty-seven cubits of each pillar, allowing for the slope of the roof to the apex, would suit well enough. But the absence of all reference to their position as parts of the building, and the entire separation of the description of their fabrication from the account of the building itself, rather favoured the other supposition, that they were isolated pillars set up in front of the porch as symbolic monuments, conveying the idea of Psalms 46, “God is our hope and strength;” “God is in the midst of her, therefore shall she not be removed.” It is particularly noticed (2Kings 25:13-16; Jeremiah 52:17; Jeremiah 52:20-23) that they were broken up by the Chaldæans. on the capture of Jerusalem, and the brass carried away. The description is exceedingly elaborate, and, except in one or two parts, clear enough. The shaft of each pillar was twenty-seven feet high, and its diameter something less than six feet. Josephus says that it was hollow, but of considerable thickness. Above the shaft was a chapiter (or capital) of great proportionate size (seven and a half feet high), covered with a net-work and festoons of metal-work, and ornamented with two rows of pomegranates, a hundred in each row. Over these again was “lily-work” of six feet in height—probably some conventionalised foliage, technically known by that name, like the “honeysuckle ornament” in classical architecture, or the conventional “dog-tooth” or “ball-flower” of Gothic. The whole height, even if there were no base or plinth below, would be twenty-seven cubits, or forty feet and a half. In the Dict. of the Bible (TEMPLE) is given a drawing of a pillar at Persepolis, which bears a considerable resemblance to the general description here given, but, being executed in stone, is far less elaborate in ornamentation. The whole style of the narrative shows that these were regarded as monuments of the highest artistic skill, and well known to all, as from their position they would be constantly before the eyes both of priests and people. There was, so far as can be seen, nothing to correspond to them in the Tabernacle.

1 Kings 7:15-16. He cast two pillars of brass — Of which see 2 Kings 25:16-17; Jeremiah 52:21. Of eighteen cubits high apiece — It is said, 2 Chronicles 3:15, that these pillars were thirty-five cubits high, which relates to the height of both of them together without their pedestals, whereas the height of each is given here with its pedestal. A line of twelve cubits did compass either of them — The diameter, therefore, was four cubits, which, considering the chapiter of five cubits, added to the height of each pillar, (2 Chronicles 3:15,) was only in due proportion to the height. In 2 Kings 25:17, indeed, it is said, that the height of the chapiter was only three cubits. But it must be observed, that the word chapiter may either be taken more largely for the whole, in which case, it was five cubits; or more strictly, either for the pommels, as they are called, 2 Chronicles 4:12; or for the cornice or crown, and so it was but three cubits, to which the pomegranates being added, made it four cubits, as it is 1 Kings 7:19, and the other work upon it took up one cubit more, which in all made five cubits.

7:13-47 The two brazen pillars in the porch of the temple, some think, were to teach those that came to worship, to depend upon God only, for strength and establishment in all their religious exercises. Jachin, God will fix this roving mind. It is good that the heart be established with grace. Boaz, In him is our strength, who works in us both to will and to do. Spiritual strength and stability are found at the door of God's temple, where we must wait for the gifts of grace, in use of the means of grace. Spiritual priests and spiritual sacrifices must be washed in the laver of Christ's blood, and of regeneration. We must wash often, for we daily contract pollution. There are full means provided for our cleansing; so that if we have our lot for ever among the unclean it will be our own fault. Let us bless God for the fountain opened by the sacrifice of Christ for sin and for uncleanness.These famous pillars, which were broken in pieces by the Babylonians when they destroyed Jerusalem 2 Kings 25:13; Jeremiah 52:17, were probably for ornament, standing by themselves under or in front of the porch. It is certain that the Phoenicians used isolated metal columns as sacred ornaments, so that Hiram would be familiar with such a mode of ornamentation. Eighteen cubits appear to have been the height of the shaft only. Adding the capital 1 Kings 7:16, 1 Kings 7:19, the entire metal pillar was 27 cubits high; and if it had a stone base of eight cubits, which would not be greatly out of proportion, the height of 35 cubits (52 12 feet, 2 Chronicles 3:15) would have been reached. The height of some of the Persepolitan columns, with which these pillars may be best compared, is 67 feet. The circumference of 12 cubits (18 feet) implies a diameter of about 5 feet 9 inches at the base, which would make the column somewhat heavy in appearance. Egyptian pillars were, however, even thicker in proportion to their height. On the supposition that a portion of the original text has fallen out, this verse has been thus completed: "He cast two pillars of brass; eighteen cubits was the height of the one pillar, and eighteen cubits was the height of the other pillar; and a line of twelve cubits compassed the one pillar, and a line of twelve cubits compassed the other pillar." 15-22. two pillars of brass of eighteen cubits high—They were made of the brass (bronze) which was taken from the king of Zobah (1Ch 18:8). In 2Ch 3:15 they are said to have been thirty-five cubits high. There, however, their joint lengths are given; whereas here the length of the pillars is given separately. Each pillar was seventeen and a half cubits long, which is stated, in round numbers, as eighteen. Their dimensions in English measure are as follows: The pillars without the capitals measured thirty-two and a half feet long, and seven feet diameter; and if hollow, as Whiston, in his translation of Josephus, thinks (Jer 52:21), the metal would be about three and a half inches thick; so that the whole casting of one pillar must have been from sixteen to twenty tons. The height of the capitals was eight and three-fourths feet; and, at the same thickness of metal, would not weigh less than seven or eight tons each. The nature of the workmanship in the finishing of these capitals is described (1Ki 7:17-22). The pillars, when set up, would stand forty feet in height [Napier, Metal]. He cast two pillars of brass; of which see 2 Kings 25:16,17 Jer 52:21.

Of eighteen cubits high apiece.

Object. They are said to be thirty-five cubits high, 2 Chronicles 3:15.

Answ. That place manifestly speaks of both the pillars; and this of each, or one pillar, as it is in the Hebrew.

Object. But then it should have been thirty-six cubits.

Answ. Either the odd half cubit is swallowed up either in the top of the chapiter, or in the bottom of the basis of each pillar; or it is neglected in the account, as commonly small measures or numbers are.

Line of twelve cubits did compass either of them about; so the diameter was four cubits, which, considering the chapiter of five cubits added to the height of each pillar, 2 Chronicles 3:14, was not unproportionable to the height.

For he cast two pillars of brass, eighteen cubits high apiece,.... In 2 Chronicles 3:15 they are said to be thirty five cubits high, which must be understood of the length or height of them both; and whereas that would allow but seventeen cubits and a half to a pillar, either the round number of eighteen is used, or half a cubit in each may be allowed, either for the base or pedestal into which they were put; or the chapiter at the top of them, into which they might go such a length, and so only what was seen is described:

and a line of twelve cubits did compass either of them about; that was the circumference of them, and therefore their diameter must be four cubits. Eupolemus, an Heathen writer (n) speaks of these pillars, but he makes the circuit of them to be but ten cubits; and says they were equal in height with the temple, and stood on the right and left, and were made of brass, and covered with gold, the thickness of a finger.

For he cast two pillars of brass, of eighteen cubits high apiece: and a line of twelve cubits did compass either of them about.
