'Volunteer' in the Bible

" 'This will be the sign for you: Eat the volunteer plants for the year, and in the second year, the volunteer plants that spring up from that. But [in] the third year, sow and reap, plant vineyards and eat their fruit.

Your people {will volunteer} in the day of your power. In holy splendor, from [the] womb of [the] dawn, you will have the dew of your youth.

And this [shall be] the sign for you: the eating of volunteer plants this year, and in the second year self-seeded plants, and in the third year sow, reap, plant vineyards, and eat their fruit.
