These following passages in the Bible show that imagination can sometimes get the best of our fears.

(1) Genesis 32, 33:

⁶ When the messengers returned to Jacob, they said, “We went to your brother Esau, and now he is coming to meet you, and four hundred men are with him.”

⁷ In great fear and distress Jacob divided the people who were with him into two groups, and the flocks and herds and camels as well. ⁸ He thought, “If Esau comes and attacks one group, the group that is left may escape.”

⁹ Then Jacob prayed, “O God of my father Abraham, God of my father Isaac, Lord, you who said to me, ‘Go back to your country and your relatives, and I will make you prosper,’ ¹⁰ I am unworthy of all the kindness and faithfulness you have shown your servant. I had only my staff when I crossed this Jordan, but now I have become two camps. ¹¹ Save me, I pray, from the hand of my brother Esau, for I am afraid he will come and attack me, and also the mothers with their children. ¹² But you have said, ‘I will surely make you prosper and will make your descendants like the sand of the sea, which cannot be counted.’”

⁴ But Esau ran to meet Jacob and embraced him; he threw his arms around his neck and kissed him. And they wept. ⁵ Then Esau looked up and saw the women and children. “Who are these with you?” he asked.

(2) Genesis 43:

¹⁶ When Joseph saw Benjamin with them, he said to the steward of his house, “Bring the men into the house, and slaughter an animal and make ready, for the men are to dine with me at noon.” ¹⁷ The man did as Joseph told him and brought the men to Joseph’s house. ¹⁸ And the men were afraid because they were brought to Joseph’s house, and they said, “It is because of the money, which was replaced in our sacks the first time, that we are brought in, so that he may assault us and fall upon us to make us servants and seize our donkeys.” ¹⁹ So they went up to the steward of Joseph’s house and spoke with him at the door of the house, ²⁰ and said, “Oh, my lord, we came down the first time to buy food. ²¹ And when we came to the lodging place we opened our sacks, and there was each man’s money in the mouth of his sack, our money in full weight. So we have brought it again with us, ²² and we have brought other money down with us to buy food. We do not know who put our money in our sacks.” ²³ He replied, “Peace to you, do not be afraid. Your God and the God of your father has put treasure in your sacks for you. I received your money.” …

(3) Numbers 13

²⁵ At the end of forty days they returned from spying out the land. ²⁶ And they came to Moses and Aaron and to all the congregation of the people of Israel in the wilderness of Paran, at Kadesh. They brought back word to them and to all the congregation, and showed them the fruit of the land. ²⁷ And they told him, “We came to the land to which you sent us. It flows with milk and honey, and this is its fruit. ²⁸ However, the people who dwell in the land are strong, and the cities are fortified and very large. And besides, we saw the descendants of Anak there. ²⁹ The Amalekites dwell in the land of the Negeb. The Hittites, the Jebusites, and the Amorites dwell in the hill country. And the Canaanites dwell by the sea, and along the Jordan.”

³⁰ But Caleb quieted the people before Moses and said, “Let us go up at once and occupy it, for we are well able to overcome it.” ³¹ Then the men who had gone up with him said, “We are not able to go up against the people, for they are stronger than we are.” ³² So they brought to the people of Israel a bad report of the land that they had spied out, saying, “The land, through which we have gone to spy it out, is a land that devours its inhabitants, and all the people that we saw in it are of great height. ³³ And there we saw the Nephilim (the sons of Anak, who come from the Nephilim), and we seemed to ourselves like grasshoppers, and so we seemed to them.”
