17 There were lattices of checker work with wreaths of chain work for the capitals on the tops of the pillars, a lattice[1] for the one capital and a lattice for the other capital. 18 Likewise he made pomegranates[2] in two rows around the one latticework to cover the capital that was on the top of the pillar, and he did the same with the other capital. 19 Now the capitals that were on the tops of the pillars in the vestibule were of lily-work, four cubits. 20 The capitals were on the two pillars and also above the rounded projection which was beside the latticework. There were two hundred pomegranates in two rows all around, and so with the other capital. 21 He set up the pillars at the vestibule of the temple. He set up the pillar on the south and called its name Jachin, and he set up the pillar on the north and called its name Boaz.

Commentary on 1 Kings 7:13-47
(Read 1 Kings 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.
