The Lord... gave them a charge. — The reluctance and opposition of Moses led to an express “charge” being laid upon himself and Aaron, the details of which are given in Exodus 7:1-9; Exodus 6:1 of Exodus 7 probably followed originally on Exodus 6:12 of this chapter. When the genealogy was inserted at this point, the present verse, which summarises Exodus 7:1-9, was added, as also Exodus 6:28-30 at the end of the chapter.
