מדרש על ישעיהו 58:9

Our Rabbis were taught: He who loves his wife as himself and honors her even more than himself, and he who leads his sons and daughters on the right path and marries them off near their period of puberty, concerning him the passage reads (Ib.) And thou shalt know that there is peace in thy tent. Our Rabbis were taught: He who loves his neighbors, befriends his relatives, marries his brother's daughter, (Fol. 63) and who lends money to the poor when in distress, concerning him the passage says (Is. 58, 9) Then shalt thou call, and the Lord will answer: Thou shalt cry, and He will say, "Here am I."

(Exod. 3:3:) SO MOSES SAID: I MUST TURN ASIDE TO LOOK. R. Johanan said: Moses walked three steps.⁶⁵Tanh., Exod. 1:15; cf. Exod. R. 2:6. Resh Laqish said: he did not walk but merely twisted his neck (to look). The Holy One said to him: You took the trouble to look. By your life I will appear to you. Immediately (in Exod. 3:4): GOD CALLED UNTO HIM FROM THE MIDST OF THE THORN BUSH AND SAID: MOSES, MOSES! AND HE SAID: HERE I AM. The Holy One said to him: You have said: HERE I AM. By your life, the hour will come when you will say a prayer over Israel, and I will immediately answer you <with these words>. It is so stated (in Is. 58:9): THEN, WHEN YOU CALL, THE LORD SHALL ANSWER; WHEN YOU CRY FOR HELP, HE SHALL SAY: HERE I AM.

And Moses said: I will turn aside now, and see this great sight (Exod. 3:3). R. Johanan held that Moses took three steps forward. R. Simeon the son of Lakish insisted that he did not step forward at all but simply turned his neck to observe it. The Holy One, blessed be He, said to him: Because you troubled to look, be assured you will merit that I shall reveal Myself unto you. Forthwith, And God called unto him out of the midst of the bush (ibid., v. 4). The Holy One, blessed be He, said to him: Because you responded Here am I, be assured that the time will come when you will pray on behalf of Israel and I will answer you at once, with the same words: Then shalt thou call, and the Lord will answer; thou shalt cry, and He will say: “Here am I” (Isa. 58:9).
