Adam Clarke

He is God in heaven above, and to earth beneath - This confession of the true God is amazingly full, and argues considerable light and information. As if she had said, "I know your God to be omnipotent and omnipresent:" and in consequence of this faith she hid the spies, and risked her own life in doing it. But how had she this clear knowledge of the Divine nature? 1. Possibly the knowledge of the true God was general in the earth at this time, though connected with much superstition and idolatry; the people believing that there was a god for every district, and for every people; for the mountains and for the valleys; see Kg1 20:23. 2. Or she received this instruction from the spies, with whom she appears to have had a good deal of conversation; or, 3. She had it from a supernatural influence of God upon her own soul. She probably made a better use of the light she had received than the rest of her countrymen, and God increased that light.
