'Former Days' in the Bible

And he shall separate to LORD the days of his separation, and shall bring a he-lamb a year old for a trespass-offering. But the former days shall be void, because his separation was defiled.

Say thou not, What is the cause that the former days were better than these? For thou do not inquire wisely concerning this.

But now I will not be to the remnant of this people as in the former days, says LORD of hosts.
