Targum su Numeri 9:8

This is one of four matters of judgment brought before Mosheh the prophet, which he decided according to the Word of the Holy One: in some of which Mosheh was deliberate, because they were judgments about life; but in the others Mosheh was prompt, they being (only) judgments concerning money: but in those (the former) Mosheh said, I have not heard; that he might teach the princes of the Sanhedrin who should arise after him to be deliberate in judgements regarding life, but prompt in judgments about money; and not to be ashamed to ask counsel in things too hard for them, inasmuch as Mosheh himself, the Rabbi of Israel, had need to say, I have not yet heard. Therefore, said Mosheh to them, Wait until I have heard what will be commanded from before the Lord concerning your case.

This is one of four matters of judgment brought before Mosheh, in two of which Mosheh was prompt, and in two was he slower. Concerning the unclean who could not perform the Pascha in its time, and concerning the daughters of Zelophehad, was Mosheh prompt, because the latter judgment was about money; but concerning the blasphemer who had reviled the sacred Name, and the gatherer of wood, who wickedly profaned the Sabbath, Mosheh was deliberate, they being decisions involving life; and in them he said, I have not heard; that he might teach the judges who were to come after Mosheh to be prompt in cases of mammon, but deliberate in those of life; and not to be ashamed to say, I have not heard, because Mosheh our Rabbi himself said, I have not heard. Therefore, spake he, Arise, and listen to what the Word of the Lord will prescribe to you.
