“Until the harvest,” “until the vintage,” “until the olive-picking” —- it is forbidden only until [these times] arrive.  This is the rule: Whatever has a set time, and he said: “until it arrives,” it is forbidden until it arrives; [if] he said: “until it is,” it is forbidden until it ends. Whatever has no set time —- whether he said: “until it is,” or whether he said: “until it arrives” —- it is forbidden only until it arrives.
