The prophet Isaiah chose a woman in Israel who was also a prophet indicating that they shared an understanding of God’s plans and directions (Isa 8:3). There weren’t many women in the Old Testament who possessed prophetic gifts – she happens to be the 4th woman called a prophetess in Israel after Miriam (Exod. 15:20), Deborah (Judg. 4:4), and Huldah (2 Kings 22:14; 2 Chron. 34:22).
They had 2 sons whose names broadcasted short prophetic stories, thus showing her devotion, alongside Isaiah, to proclaim the purposes of God. We may not have it recorded what she said, but these names told all and sundry, every day, what she believed.
This begs the question—what is there about your life that publicises that you follow Jesus?
Jesus told us that there are 3 actions that will define you as a Christian: deny yourself, take up your cross and follow Jesus, surrendering to His lead. This means that we are called upon to forget our self-interests and self-preservation and serve others. It means not following the herd and this world’s authority figures and following the narrative that Jesus gave us, a life of sacrifice so that others may be saved.
“If any of you wants to be my follower, you must give up your own way, take up your cross, and follow me. If you try to hang on to your life, you will lose it. But if you give up your life for my sake and for the sake of the Good News, you will save it’” (Mark 8:34-35 NLT).
Following Jesus was a price that Isaiah’s wife believed well worth paying and she stated in the most forthright way she could that the Lord was bringing judgments on this world and make sure you are in the protected remnant (I Cor. 14:8). Her prophetic vision reaches to today for the names of her sons were Shear-jashub, meaning "A remnant shall return", and Maher-Shalal-Hash-Baz, meaning, "Spoil quickly, plunder speedily."
