A frightened question aims the eyes at the threat and leaves the resources standing unseen on the same ground.
Asked in a rush, what do we do now works as a scanning instruction, sending the mind out to count enemy horses, and it returns an accurate and complete inventory of everything able to kill a person. Accuracy is what makes the filter convincing; nothing in the count is false, and the count is still wrong.
The man of God prays for opened eyes rather than for reinforcements, because the second army was in position before the servant ever woke. What needed changing was the search, not the supply. Running the panic question costs a person the strength they spend bracing for a defeat the full facts never required.
