Commentary for I Kings 7:51

The sacred of his father Dovid. That which remained of the silver and gold dedicated by his father. But the Midrash explains that Shlomo did not wish to use any of those dedicated materials for the construction of the Beis [Hamikdosh]. And I heard from [Torah] scholars of Yisroel who said, because Dovid knew eventually it would be destroyed; so that the idol worshiping [nations] should not say that their idols are mightier for they took their revenge upon the Beis [Hamikdosh] which was built of the plunder and destruction which Dovid plundered from them. And others say, Shlomo said that there was a famine in the days of his father for three consecutive years, and he should have squandered these dedicated materials to sustain Yisroel’s poor.
