Numbers 33:7-8
33:7 They traveled from Etham, and turned again to Pi-hahiroth, which is before Baal-Zephon; and they camped before Migdal.
33:8 They traveled from Pi-hahiroth, 1 and passed through the middle of the sea into the wilderness, and went three days’ journey in the wilderness of Etham, and camped in Marah.
1 tc So many medieval Hebrew manuscripts, Smr, Syriac, and Latin Vulgate. Other witnesses have “from before Hahiroth.”
