You will surely be tested in your possessions and in yourselves. And you will surely hear from those who were given the Scripture before you and from those who associate others with Allāh much abuse. But if you are patient and fear Allāh - indeed, that is of the matters [worthy] of resolve.

۞ لَتُبْلَوُنَّ (You will certainly be tested) is passive — the action is happening to someone, but who is doing it is not mentioned.
We translate it as "is/was [done]" — e.g. "was created", "is known".
Lesson 11 · Passive & Participles۞ لَتُبْلَوُنَّ (You will certainly be tested) uses form IV (أَفْعَلَ) — the أ at the start makes it causative ("to make someone do something").
We translate it as "to make [someone] do" or "to cause [action]".
Lesson 12 · Verb Families II–IV۞ لَتُبْلَوُنَّ (You will certainly be tested) starts with لَ for emphasis — it's like saying "indeed!" or "certainly!".
We add "indeed" or "certainly" to show the emphasis.
