Jeremiah 1:15 For behold I will call together all the families of the kingdoms of the north, saith the Lord: and they shall come, and shall set every one his throne in the entrance of the gates of Jerusalem, and upon all the walls thereof round about, and upon all the cities of Juda.

The verse centers on "behold", "call", "together", "families", "kingdoms", "north", "saith", and "lord". It is saying that the verse draws attention to "behold" and "call", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 14's "And the Lord said to me From..." into verse 16's "And I will pronounce my judgments against...", so "behold" and "call" belong inside that flow. In Jeremiah context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "behold" and "call" with trust shaped by these words, not by a vague optimism outside the passage.
