"a sign"
37:30 And this shall be a sign unto thee, Ye shall eat this year such as groweth of itself; and the second year that which springeth of the same: and in the third year sow ye, and reap, and plant vineyards, and eat the fruit thereof.
37:31 And the remnant that is escaped of the house of Judah shall again take root downward, and bear fruit upward:
37:32 For out of Jerusalem shall go forth a remnant, and they that escape out of mount Zion: the zeal of the LORD of hosts shall do this.
