17 He made a lattice network, with wreaths of chainwork, for the capitals which were on top of the pillars: seven chains for one capital and seven for the other capital. 18 So he made the pillars, and two rows of pomegranates above the network all around to cover the capitals that were on top; and thus he did for the other capital. 19 The capitals which were on top of the pillars in the hall were in the shape of lilies, four cubits. 20 The capitals on the two pillars also had pomegranates above, by the convex surface which was next to the network; and there were two hundred such pomegranates in rows on each of the capitals all around. 21 Then he set up the pillars by the vestibule of the temple; he set up the pillar on the right and called its name Jachin, and he set up the pillar on the left 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.
