After their journeys,—and pitched in Rephidim— See Numbers 33:12-14. Rephidim was a dry and sandy part of the desert of Sin, within a march or two of Sinai; where, there being no water for the people to drink, and that which they brought from Elim being spent, their usual temper predominated, and they murmured against Moses for water now, as they had done for bread before. See ch. Exodus 16:2-3 and Numbers 20:4.
