"The Lord has returned our captivity. Rabbi Yitzchak said: The day of rain is as great as the resurrection of the dead, as it is written: "The Lord has returned our captivity as streams in the Negev." And there are no streams except for rain, as it says: "And they saw the streams of the sea." Those who sow in tears will reap with joy.
Rabbi Yehuda said: When a bull walks and cries, on its return it eats from the same mound. Another explanation: Those who sow in tears are referring to Jacob, who sowed blessings with tears. "He will reap with joy" (Genesis 27:28) and God will give you. "He went, he walked, and he cried" (Genesis 29:11) and he raised his voice and wept.
The one who sows will bear the burden of the seed, as the tribes are compared to a burden. He who comes, comes with joy, bearing his sheaves. I implore my worlds and all worlds."
