Joshua 2:8-13

Verse 9

I know that the Lord hath given you the land - It is likely she had this only from conjecture, having heard of their successes against the Amorites, their prodigious numbers, and seeing the state of terror and dismay to which the inhabitants of her own land were reduced.
Verse 11

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 1Kgs 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.
Verse 12

Swear unto me by the Lord - This is a farther proof that this woman had received considerable instruction in the Jewish faith; she acknowledged the true God by his essential character Jehovah; and knew that an oath in his name was the deepest and most solemn obligation under which a Jew could possibly come. Does not this also refer to the command of God, Thou shalt fear the Lord, and shalt swear by his name? See the note on Deu 6:13.
Verse 13

Deliver our lives from death - She had learned, either from the spies or otherwise, that all the inhabitants of the land were doomed to destruction, and therefore she obliges them to enter into a covenant with her for the preservation of herself and her household.
