이사야 59:16의 Musar

On the absence of this, the prophets complained saying: "And He saw that there was no man, and He was astounded for there was no intercessor"(Yeshaya 59:16) and "I looked, and there was none to help; and I was astonished that there was no one to uphold" (Yeshaya 63:5). And it is stated: "it is Zion; no one inquires after her" (Yirmiyahu 30:17), which our sages expounded: "this implies it needs inquiring after" (Sukkah 41a).

Thus we learn from here that we are obligated in this matter, and cannot exempt ourselves due to our lack of power. For on all such matters, we learned: "It is not incumbent upon you to complete the task, but neither are you free to abstain from it" (Avot 2:16).
