Chp. 16 verse 27 - Chp. 17: Hashem questions Moshe about the peoples' sincerity. They name the heavenly food "mann" and Moshe puts some in a jar to be saved for eternity. Chp. 17, the people travel to Rephidim and they demand that Moshe give them water. Hashem instructs Moshe to hit the rock and it would give forth water. They call the place Massah and Meribah. Amalek comes and attacks the nation. Moshe tells Yehoshua to take men and battle with them and he defeats them. Hashem tells Moshe about the command to wipe out the memory of Amalek.
