a The prefix conjugation is used to represent a real situation which arises as a consequence of some other situation. Whereas the suffix conjugation may dramatically represent a future situation as an accidental event, the prefix conjugation represents it as a logical consequence of some expressed or unexpressed situation. Though Michel overextends the concept of dependency to all uses of the prefix conjugation, he has plausibly suggested that substantiality in contrast to accidence is one of the differences between the conjugations.
This use overlaps with some of the modal nuances, which also involve dependency, especially those of capability, of obligation, and of deliberation.
1. כִּי בְּיוֹם אֲכָלְךָ מִמֶּנּוּ מוֹת תָּמוּת׃
…because when you eat of it you shall surely die.
He who does these things will (or, can) never be shaken.
Who does not swear by what is false,34 he will (must) receive blessing from Yhwh.
All who hope in you will (can) not be put to shame; they will (must) be put to shame who are vainly treacherous.
Yhwh is my light and my salvation; whom shall (should) I fear?
