Although these precious things are not explicitly identified, the context makes clear that it refers to the plundering of the temple by the Babylonians. 2 Kings 25:13–17 provides a list of all the spoils carried to Babylon. Beyond temple items, these spoils include jewellery and personal belongings of the residents of Jerusalem and Judah.1
10 The enemy has stretched out his hands over all her precious things; for she has seen the nations enter her sanctuary, those whom you forbade to enter your congregation.
