35 Then Jesus went throughout all the towns and villages, teaching in their synagogues, preaching the good news of the kingdom, and healing every kind of disease and sickness. 36 When he saw the crowds, he had compassion on them because they were bewildered and helpless, like sheep without a shepherd. 37Then he said to his disciples, “The harvest is plentiful, but the workers are few.38Therefore ask the Lord of the harvest to send out workers into his harvest-ready fields.”

Pirkei Avot 2:15
13 Rabbi Shimon said: Be careful with the reading of Shema and the prayer, And when you pray, do not make your prayer something automatic, but a plea for compassion before God, for it is said: “for he is gracious and compassionate, slow to anger, abounding in kindness, and renouncing punishment” (Joel 2:13); And be not wicked in your own esteem. 14 Rabbi Elazar said: Be diligent in the study of the Torah; And know how to answer an epicuros, And know before whom you toil, and that your employer is faithful, for He will pay you the reward of your labor. 15Rabbi Tarfon said: the day is short, and the work is plentiful, and the laborers are indolent, and the reward is great, and the master of the house is insistent.16 He [Rabbi Tarfon] used to say: It is not your duty to finish the work, but neither are you at liberty to neglect it; If you have studied much Torah, you shall be given much reward. Faithful is your employer to pay you the reward of your labor; And know that the grant of reward unto the righteous is in the age to come.
