Verse 34. - And there were four under setters [it seems probable that this is not a repetition of ver. 30 (Rawlinson), but that the reference is to the upper part (cf. ver. 35) of the shoulder pieces, which, according to Keil's view, supported the laver] to the four corners of one base: and the undersetters were of the very base itself. [Heb. from the base, its shoulders. Whether these words mean that the shoulders projected from the base, that "they rose above the corners with a slight curve" (Keil), or that they were cast with the base, i.e., from the same mould, as in the next verse, it is impossible to say.]
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.
and the undersetters were of the base itself; they were cast together, and of the same piece of metal with it.
