John Calvin on Exodus 18:3-4

3. And her two sons. It was remarked in its proper place, how distinguished a proof not only of faith, but of magnanimity and firmness Moses had manifested in giving these names to his sons. For we cannot doubt, but that he brought on himself the ill-will of his connections, as if he despised the country of his wife, by calling the one (Gershom) “a strange land;” and the name of his son continually cried out, that though he inhabited Midian, yet was he an alien in his heart, and though sojourning for a time, would afterwards seek another habitation. Whence also we may conjecture that he took them with him into Egypt, rather than banish from him these two pledges of his piety on account of the sudden anger and reproaches of his wife; since by their names he was daily reminded that God’s covenant was to be, preferred to all earthly advantages.
