Matthew Poole and continuators on Numbers 14:34

34 After the number of the dayes in which ye searched the land, even fourty dayes (each day for a year ) shall ye bear your iniquities, even fourty years, and ye shall know my breach of promise .

So there should have been 40 years to come, but God was pleased mercifully to accept of the time past as a part of that time.

That as you have first broken the covenant between you and me by breaking the terms or conditions of it, so I will make it void on my part, by denying you the blessings promised in that covenant and to be given to you in case of your obedience. So you shall see that the breach of promise wherewith you charged me, ver. 3. lies at your door and was forced from me by your perfidiousness. Or, my breach, either passively, i. e. your breaking off from me, as such pronouns are oft used, as Gen. 50. 4. Isa. 53. 11. and 56. 7. or actively, i. e. my breaking of or departing from you, and stopping the current of my blessings towards you: you shall feel by experience, how sad your condition is when I withdraw my grace and favour from you.
