(Proverbs 18:11) 11 The valuable things of the rich are his strong town, and they are like a protective wall in his IMAGINATION(my caps) . ".
(Psalm 96:4-6) 4 For Jehovah is great and very much to be praised. He is fear-inspiring above all [other] gods. 5 For all the gods of the peoples are valueless gods; But as for Jehovah, he has made the very heavens. 6 Dignity and splendor are before him; . . ."

(Joshua 2:8-12) . . .As for these, before they could lie down, she herself came up to them on the roof. 9 And she went on to say to the men: “I do know that Jehovah will certainly give YOU the land, and that the fright of YOU has fallen upon us, and that all the inhabitants of the land have become disheartened because of YOU.
10 For we have heard how Jehovah dried up the waters of the Red Sea from before YOU when YOU came out of Egypt, and what YOU did to the two kings of the Am′or‧ites who were on the other side of the Jordan, namely, Si′hon and Og, whom YOU devoted to destruction. 11 When we got to hear it, then our hearts began to melt, and no spirit has arisen yet in anybody because of YOU, for Jehovah YOUR God is God in the heavens above and on the earth beneath.
