'Conceived' in the Bible

I went to the prophetess, and she conceived, and bore a son. Then Yahweh said to me, "Call his name 'Maher Shalal Hash Baz.'

Then you will say in your heart, 'Who has conceived these for me, since I have been bereaved of my children, and am solitary, an exile, and wandering back and forth? Who has brought up these? Behold, I was left alone; these, where were they?'"
