John4
We are commanded to work in the harvest/regathering of the lost sheep of Israel.
35“Do you not say, ‘There are still four months, and the harvest comes’? See, I say to you, lift up your eyes and see the fields, for they are white for harvest – already!
36“He who is reaping receives a reward, and gathers fruit for everlasting life, so that both he who is sowing and he who is reaping rejoice together.
37“For in this the word is true, ‘One sows and another reaps.’
38“I sent you to reap that for which you have not laboured. Others have laboured, and you have entered into their labours.”
The house of Israel and the house of Yehudah will become one again in the second exodus. As we, Israel are being regathered in the second exodus we await the regathering of Judah.
Jer 3
18“In those days the house of Yehuḏah shall go to the house of Yisra’ĕl, and they shall come together out of the land of the north to the land that I have given as an inheritance to your fathers.
