Targum zu Bamidbar 12:12

I entreat thee that Miriam, our sister, may not be defiled with leprosy in the tent, as the dead, for it is with her as with the infant which, having well fulfilled the time of the womb, perishes at the birth: so Miriam was with us in the land of Mizraim, seeing us in our captivity, our dispersion, our servitude; but now, when the time hath come for our going forth to possess the land of Israel behold she is kept back from us. I entreat thee, my lord, to pray for her, that her righteousness may not come to nought among the congregation.

Let not Miriam, our sister, be a leper, polluted in the tent as one dead. For it is with her as with the infant who hath passed nine months in its mother's womb, in water and in heat, without injury, but which after all perishes at the birth. So was Miriam, our sister, carried away with us into the desert, and with us in our trouble; but now the time hath come that we may enter into the land of Israel, why should she be kept from us? Pray now for the dead body that it may live, and that her righteousness may not fail.
