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.

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].
