Today's Favorite Verse: Genesis 35:5
"And they journeyed: and the terror of God was upon the cities that were round about them, and they did not pursue after the sons of Jacob."
It was the word "terror" that stood out to me. It reminded me of this verse where Zion is called terrible.
"And it shall be said among the wicked: Let us not go up to battle against Zion, for the inhabitants of Zion are terrible; wherefore we cannot stand."
(Doctrine and Covenants 45:70)
I looked for why Zion is called terrible and I found these two quotes.
"The priests of Christendom now say, “We cannot stand before this man,” and they warn their flocks to keep away from the Latter-day Saints. “Are you reading that ‘Voice of Warning?’ Lay it out of your hands and put it out of your houses, for it is a dangerous book. Put away from you their tracts and books, for they are dangerous; and keep away, keep away from those dangerous men that are turning the world upside down.” That is the cry throughout the world. What will be the cry when they come up against us and try the force of arms? It will be—“Let us not go up against Zion, for the people thereof are terrible: keep away, keep away.” The one cry follows in the wake of the other. What makes the people of Zion terrible? Answer: Strict honesty and integrity before God. That is what will bring the cloud by day and the shining of a flame of fire by night; and upon all the glory there shall be a defense. God will surround the people of Zion as it were with a wall of fire, and he will make bare his arm in the eyes of the nation that wars against her, and she will be like a beacon light to seafaring men; and men will come and bring their clothing and their treasures, and we shall have an abundant supply of such things. Let us take care of what we have, keep it clean and patch it up, take care of our sheep and raise all the flax and wool we can, and the Lord will make up the balance; and if we do right we shall find that we have an overflowing treasury of every good thing; which may God grant, for Christ's sake. Amen."
(Orson Hyde, "Opposition to the Gospel, Etc.", JD 6:53)
"For when the Lord shall appear he shall be terrible unto them, that fear may seize upon them, and they shall stand afar off and tremble."
(Doctrine and Covenants 45:74)
"Therefore he is gathering us here, that we may become like unto one body, being sanctified, and become, as another revelation says, “as fair as the sun, as clear as the moon, that the banners of my people may be terrible unto all the nations of the earth. Why terrible? Because of the power of the Lord which will be in the midst of his people, because of the manifestations of heaven unto his people, because the nations will hear that God is indeed in the midst of Zion. They will hear all these things, and the wicked will fear and tremble. They will fear because of their iniquity; fear and tremble, because of their wickedness; fear and tremble, because they have supported all manner of wickedness and corruption, division and strife, and abominations of every kind in their midst. Therefore fearfulness will seize upon them, and they will know of a surety that the Lord God is in the midst of the people of Zion, that his power is there, that his spirit is there, and that he manifests himself there in great glory. Amen."
(Orson Pratt, "The Priesthood, Etc.", JD 18:362)
I think its not so much the actions of Zion make her terrible, it's because the presence of the Lord is with her.
"And the day shall come when the nations of the earth shall tremble because of her, and shall fear because of her terrible ones. The Lord hath spoken it. Amen."
(Doctrine and Covenants 64:43)
"And, now, behold, if Zion do these things she shall prosper, and spread herself and become very glorious, very great, and very terrible.
And the nations of the earth shall honor her, and shall say: Surely Zion is the city of our God, and surely Zion cannot fall, neither be moved out of her place, for God is there, and the hand of the Lord is there;"
(Doctrine and Covenants 97:18-19)
"But first let my army become very great, and let it be sanctified before me, that it may become fair as the sun, and clear as the moon, and that her banners may be terrible unto all nations;"
(Doctrine and Covenants 105:31)
