As prophetess and sister of Aaron she led the chorus of women, who replied to the male chorus with timbrels and dancing, and by taking up the first strophe of the song, and in this way took part in the festival; a custom that was kept up in after times in the celebration of victories (Jdg 11:34; 1Sa 18:6-7; 1Sa 21:12; 1Sa 29:5), possibly in imitation of an Egyptian model (see my Archäologie, §137, note 8).
verses 22-24
Leaving the Red Sea, they went into the desert of Shur. This name is given to the tract of desert which separates Egypt from Palestine, and also from the more elevated parts of the desert of Arabia, and stretches from the Mediterranean to the head of the Arabian Gulf or Red Sea, and thence along the eastern shore of the sea to the neighbourhood of the Wady Gharandel. In Num 33:8 it is called the desert of Etham, from the town of Etham, which stood upon the border (see Exo 13:20). The spot where the Israelites encamped after crossing the sea, and sang praises to the Lord for their gracious deliverance, is supposed to have been the present Ayun Musa (the springs of Moses), the only green spot in the northern part of this desolate tract of desert, where water could be obtained. At the present time there are several springs there, which yield a dark, brackish, though drinkable water, and a few stunted palms; and even till a very recent date country houses have been built and gardens laid out there by the richer inhabitants of Suez. From this point the Israelites went three days without finding water, till they came to Marah, where there was water, but so bitter that they could not drink it. The first spot on the road from Ayun Musa to Sinai where water can be found, is in the well of Howâra, 33 English miles from the former. It is now a basin of 6 or 8 feet in diameter, with two feet of water in it, but so disagreeably bitter and salt, that the Bedouins consider it the worst water in the whole neighbourhood
