Adam Clarke on 2 Kings 4:23

Wherefore wilt thou go - She was a very prudent woman; she would not harass the feelings of her husband by informing him of the death of his son till she had tried the power of the prophet. Though the religion of the true God was not the religion of the state, yet there were no doubt multitudes of the people who continued to worship the true God alone, and were in the habit of going, as is here intimated, on new moons and Sabbaths, to consult the prophet.
