Jehovah God is the 'God, in heaven above and on earth beneath'

Within the list of faith champions in Hebrews 11, Rahab is mentioned right after Moses, and instead of Joshua! It was by faith that Rahab the prostitute was not destroyed with the people in her city who refused to obey God. For she had given a friendly welcome to the spies. Hebrews 11:31 Source

Joshua 2
1 Then Joshua son of Nun secretly sent two spies from Shittim. “Go, look over the land,” he said, “especially Jericho.” So they went and entered the house of a prostitute named Rahab and stayed there.

2 The king of Jericho was told, “Look, some of the Israelites have come here tonight to spy out the land.” 3 So the king of Jericho sent this message to Rahab: “Bring out the men who came to you and entered your house, because they have come to spy out the whole land.”

4 But the woman had taken the two men and hidden them. She said, “Yes, the men came to me, but I did not know where they had come from. 5 At dusk, when it was time to close the city gate, they left. I don’t know which way they went. Go after them quickly. You may catch up with them.” 6 (But she had taken them up to the roof and hidden them under the stalks of flax she had laid out on the roof.) 7 So the men set out in pursuit of the spies on the road that leads to the fords of the Jordan, and as soon as the pursuers had gone out, the gate was shut.

8 Before the spies lay down for the night, she went up on the roof 9 and said to them, “I know that the Lord has given you this land and that a great fear of you has fallen on us, so that all who live in this country are melting in fear because of you. 10 We have heard how the Lord dried up the water of the Red Sea for you when you came out of Egypt, and what you did to Sihon and Og, the two kings of the Amorites east of the Jordan, whom you completely destroyed. 11 When we heard of it, our hearts melted in fear and everyone’s courage failed because of you, for the Lord your God is God in heaven above and on the earth below.

Because Rahab believed that Jehovah God is the “God, in heaven above and on earth beneath” she disobeyed the king of Jericho and hid the two spies. She was willing to do that because they served God whom she recognised and respected as the true God.
