Joshua 2:11 Douay-Rheims

And hearing these things we were affrighted, and our heart fainted away, neither did there remain any spirit in us at your coming in: for the Lord your God he is God in heaven above, and in the earth beneath.

“Pass now, pray, to the others who were saved by repentance. Perhaps even among the women someone will say, "I have committed fornication and adultery. I have defiled my body with every excess. Can there be salvation for me?" Fix your eyes, woman, upon Rahab, and look for salvation for yourself too. For if she who openly and publicly practiced fornication was saved through repentance, will not she whose fornication preceded the gift of grace be saved by repentance and fasting? For observe how she was saved. She said only this: "Since the Lord, your God, is God in heaven above and on earth below." "Your God," she said, for she did not dare call him her God, because of her wantonness. If you want scriptural testimony of her salvation, you have it recorded in the Psalms: "I will think of Rahab and Babylon among those who know me." The salvation procured by repentance is open to men and women alike.”

“Do you see how with faith she takes on her lips the word of the Lawgiver? "And I realize that your God is up in heaven and down on the earth, and that apart from him there is no God." Rahab is a prefigurement of the church, which was at one time mixed up in the prostitution of the demons and which now accepts the spies of Christ, not the ones sent by Joshua the son of Nun, but the apostles who were sent by Jesus the true Savior. "I learned," she says, "that your God is up in heaven and down on the earth, and that apart from him there is no God." The Jews received these things and did not safeguard them; the church heard these things and preserved them. Therefore, Rahab, the prefigurement of the church, is worthy of all praise.”

“And there was no longer any spirit. [The men had no spirit (desire)] even to lie with a woman. It was said by the Sages: There was no prince or ruler who had not had [sexual] relationships with Rochav, the harlot. She was ten years old when the Bnei Yisroel went out of Egypt, and she engaged in harlotry for forty years.”

“And as soon as we had heard these things, our hearts did melt,.... Particularly what were done to the two kings of the Amorites, who, and their people, were utterly destroyed, their goods made a prey of, and their countries seized upon and possessed: neither did there remain any more courage in any man, because of you; they looked dejected in their countenances, had no heart to go about any business, trembled at the shaking of a leaf, or at the least rumour and report made that the Israelites were coming on and were at hand; they had no spirit to prepare to go out and meet them, or to defend themselves: for the Lord your God, he is God in heaven above, and in earth beneath; the Maker and Possessor of both; is the Governor of the whole universe, and does what he pleases in it; and disposes of all countries, persons, and things, as he thinks fit: this is a proof of her knowledge of the true God, and faith in him, and shows her to be a believer, and hence she is reckoned in the catalogue of believers, Heb 11:31; and her faith is proved to be of the right kind by the works she did, Jam 2:25.”

“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.”

“Beneath. This is the confession of a true convert, (Calmet) inspired by God. (Haydock) — For St. Paul commends her faith. (Hebrews xi. 31.) (Menochius) — The pagans confined the power of their idols to certain districts; the power of the true God is infinite. (Calmet)”
