Charles Ellicott Commentary Exodus 2:1

"And there went a man of the house of Levi, and took to wife a daughter of Levi." — Exodus 2:1 (ASV)

There went. —Compare Genesis 35:22; Hosea 1:3. The expression is idiomatic, and has no special force.

A man of the house of Levi. —Note the extreme simplicity of this announcement; and compare it with the elaborate legends with which Oriental religions commonly surrounded the birth of those who were considered their founders, as Thoth, Zoroaster, Orpheus. Even the name of the man is here omitted as unimportant. It is difficult to conceive anyone but Moses making such an omission.

A daughter of Levi —that is, a woman of the same tribe as himself, a descendant of Levi—not a daughter in the literal sense, which the chronology makes impossible.
