Joshua 2:9 And she said unto the men, I know that the Lord hath given you the land, and that your terror is fallen upon us, and that all the inhabitants of the land faint because of you. 10 For we have heard how the Lord dried up the water of the Red sea for you, when ye came out of Egypt; and what ye did unto the two kings of the Amorites, that were on the other side Jordan, Sihon and Og, whom ye utterly destroyed. 11 And as soon as we had heard these things, our hearts did melt, neither did there remain any more courage in any man, because of you: for the Lord your God, he is God in heaven above, and in earth beneath.
[Patriarchs & Prophets pp 492>493] All these events were known to the inhabitants of Jericho, and there were many who shared Rahab's conviction, though they refused to obey it, that Jehovah, the God of Israel, “is God in heaven above, and upon the earth beneath.” Like the men before the Flood, the Canaanites lived only to blaspheme Heaven and defile the earth. And both love and justice demanded the prompt execution of these rebels against God and foes to man. How easily the armies of heaven brought down the walls of Jericho, that proud city whose bulwarks, forty years before, had struck terror to the unbelieving spies!
The Mighty One of Israel had said, “I have given into thine hand Jericho.” Against that word human strength was powerless. “By faith the walls of Jericho fell down.” Hebrews 11:30. The Captain of the Lord's host communicated only with Joshua; He did not reveal Himself to all the congregation, and it rested with them to believe or doubt the words of Joshua, to obey the commands given by him in the name of the Lord, or to deny his authority. They could not see the host of angels who attended them under the leadership of the Son of God. They might have reasoned:
“What unmeaning movements are these, and how ridiculous the performance of marching daily around the walls of the city, blowing trumpets of rams’ horns. This can have no effect upon those towering fortifications.” But the very plan of continuing this ceremony through so long a time prior to the final overthrow of the walls afforded opportunity for the development of faith among the Israelites. It was to be impressed upon their minds that their strength was not in the wisdom of man, nor in his might, but only in the God of their salvation. They were thus to become accustomed to relying wholly upon their divine Leader.
Zechariah 4:6 Then he answered and spake unto me, saying, This is the word of the Lord, Not by might, nor by power, but by my spirit, saith the Lord of hosts.
May God add His blessing to the study of His word. "Good night" and God bless!
