Lev 26:27  “But if in spite of this you will not listen to me, but walk contrary to me, 
Lev 26:28  then I will walk contrary to you in fury, and I myself will discipline you sevenfold for your sins. 

Leviticus 26:27 comes in the middle of a long promise of contingent punishments. Israel is being warned that God will punish them if they rebel. God promises punishment upon punishment, contingent on when Israel repents. If Israel repents sooner, then they avoid what might have happened. The entire section is structured as if Israel might respond to any particular punishment and then forgo the intensified punishment.

Lev 26:18  And if in spite of this you will not listen to me, then I will discipline you again sevenfold for your sins, 
…
Lev 26:21  “Then if you walk contrary to me and will not listen to me, I will continue striking you, sevenfold for your sins. 
…
Lev 26:23  “And if by this discipline you are not turned to me but walk contrary to me, 
Lev 26:24  then I also will walk contrary to you, and I myself will strike you sevenfold for your sins. 
…
Lev 26:27  “But if in spite of this you will not listen to me, but walk contrary to me, 
Lev 26:28  then I will walk contrary to you in fury, and I myself will discipline you sevenfold for your sins. 
…
Lev 26:40  “But if they confess their iniquity and the iniquity of their fathers in their treachery that they committed against me, and also in walking contrary to me, 
Lev 26:41  so that I walked contrary to them and brought them into the land of their enemies—if then their uncircumcised heart is humbled and they make amends for their iniquity, 
Lev 26:42  then I will remember my covenant with Jacob, and I will remember my covenant with Isaac and my covenant with Abraham, and I will remember the land. 
Lev 26:43  But the land shall be abandoned by them and enjoy its Sabbaths while it lies desolate without them, and they shall make amends for their iniquity, because they spurned my rules and their soul abhorred my statutes. 

God does not foreknow when any repentance might come or if any rebellion would even materialize. This cascading list of contingencies, is itself a meta contingency.
