The narrator links the beginning of the temple-building with Israel’s exodus from Egypt (6:1), suggesting that all Israel’s history so far has been leading up to this point (cf. Exod. 15:13-17). From now on Israel is to be known as the nation which worships YHWH in this temple. If David’s bringing up the ark to Zion set the seal on his rise to kindship, then Solomon’s building of the temple confirms YHWH’s choice of David’s line. As Meyers notes (pp. 360-2), the temple is a visual symbol of the legitimacy of David’s dynasty. It represents a stable social order in which the king enjoys divine favour and upholds justice. In Kings, as in ancient Near Eastern thought generally, the political and the religious are indivisible.
