Charles Ellicott Commentary Leviticus 26:10

"And ye shall eat old store long kept, and ye shall bring forth the old because of the new." — Leviticus 26:10 (ASV)

And you shall eat old store. —Better, old store which has become old. Though they will thus multiply, there will be abundant stores for them, which become old because it will take them so long to consume them.

And bring forth the old because of the new. —Better, and remove the old on account of the new, that is, they will always have such abundant harvests that they will be obliged to remove the old stock of grain from the barns and granaries, in order to make room for the new.
