Keep some till more come.

The saying advises holding back part of what is available rather than using everything at once. Here, “till” means “until,” and “some” means a portion of the resource under discussion.

It expresses practical restraint under uncertainty: leave a reserve for the interval before replenishment. The emphasis is not on refusing to use resources altogether, but on avoiding exhaustion when future provision is expected but not yet in hand.

Use it when advising someone to ration food, money, materials, or another limited resource while awaiting a new supply. Its compressed, older-sounding phrasing suits a proverbial warning about preserving a margin rather than spending or consuming everything immediately.
