17 There were nets of checker-work, and wreaths of chain-work, for the capitals which were upon the top of the pillars; seven for the one capital, and seven for the other capital. 18 So he made the pillars; and there were two rows round about upon the one network, to cover the capitals that were upon the top of the pillars: and so did he for the other capital. 19 And the capitals that were upon the top of the pillars in the porch were of lily-work, four cubits. 20 And there were capitals above also upon the two pillars, close by the belly which was beside the network: and the pomegranates were two hundred, in rows round about upon the other capital. 21 And he set up the pillars at the porch of the temple: and he set up the right pillar, and called the name thereof Jachin; and he set up the left pillar, and called the name thereof 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.
