Isaiah 8:3 - Ellicott's Commentary On The Whole Bible

I... the prophetess... — The word may have been given by courtesy to a prophet’s wife as such. Elsewhere, however, as in the case of Deborah (Judges 4:4) and Huldah (2 Chronicles 34:22), it implies prophetic gifts. Possibly, therefore, we may think of the prophet and his wife as having been drawn together by united thoughts and counsels, in contrast with the celibate life of Jeremiah (Jeremiah 16:2), the miseries of Hosea’s marriage (Hosea 1:2), and the sudden bereavement of Ezekiel (Ezekiel 24:16-18). We may, perhaps, trace, on this view, the wife’s hand in the toilet inventory of Isaiah 3:16-24.
