Passage
And thou shalt say to them: Hear the word of the Lord, ye kings of Juda, and al Juda, and all the inhabitants of Jerusalem, that enter in by these gates.
And thou shalt say to them: Hear the word of the Lord, ye kings of Juda, and al Juda, and all the inhabitants of Jerusalem, that enter in by these gates.
Jeremiah 17:18 Let them be confounded that persecute me, and let not me be confounded: let them be afraid, and let not me be afraid: bring upon them the day of affliction, and with a double destruction, destroy them.
Jeremiah 17:19 Thus saith the Lord to me: Go, and stand in the gate of the children of the people, by which the kings of Juda come in, and go out, and in all the gates of Jerusalem:
Jeremiah 17:20 And thou shalt say to them: Hear the word of the Lord, ye kings of Juda, and al Juda, and all the inhabitants of Jerusalem, that enter in by these gates.
Jeremiah 17:21 Thus saith the Lord: Take heed to your souls, and carry no burdens on the sabbath day: and bring them not in by the gates of Jerusalem.
Jeremiah 17:22 And do not bring burdens out of your houses on the sabbath day, neither do ye any work: sanctify the sabbath day, as I commanded your fathers.
The verse centers on "thou", "shalt", "hear", "word", "lord", "kings", and "juda". It is saying that the verse draws attention to "thou" and "shalt", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 19's "Thus saith the Lord to me Go..." into verse 21's "Thus saith the Lord Take heed to...", so "thou" and "shalt" 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 "thou" and "shalt" with trust shaped by these words, not by a vague optimism outside the passage.
