The verse centers on "shall", "come", "pass", "families", "land", "jerusalem", and "adore". It is saying that the verse draws attention to "shall" and "come", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 16's "And all they that shall be left..." into verse 18's "And if the family of Egypt go...", so "shall" and "come" belong inside that flow. In Zechariah context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "shall" and "come" with trust shaped by these words, not by a vague optimism outside the passage.
