I saw the Lord standing beside the altar, and he said, "Strike the tops of the pillars, that the thresholds may shake; and break them in pieces on the head of all of them; and I will kill the last of them with the sword: there shall not one of them flee away, and there shall not one of them escape.
This verse is therefore a prophecy of the destruction of the temple in Jerusalem, with the implied end of the kingdom and of the dynasty of David at the same time.  Most Biblical exegetes seem to be unaware of what the Old Testament says of that Solomonic temple.  To begin with, it was never God's idea at all, but David's  (2 Samuel 7).  It stood in exactly the same relationship to the tabernacle (which God indeed had given the people) as that in which the secular monarchy stood to the theocracy, namely, a rejection of it, neither the monarchy nor the temple ever being, in any sense whatever the true will of God. The Christian martyr Stephen made this abundantly clear in  Acts 7:44-50.  The summary and final end of the northern kingdom had just been announced in preceding verses; and, in this passage, preparatory to the prophecy of the eternal kingdom of the Messiah, Amos made it clear that neither the northern nor the southern kingdom, in their corporate existence, would in any manner enter into the eternal purpose of God regarding the "true Israel," which was never identified with either one of them.
