Devarim 1:17

Verse 17. No worldly end is to be had in view in deciding on the best course. Those which would be disadvantageous from a worldly point of view must be considered equally with those which would be advantageous, nor must the mind be careful about the result in this world, for all things are overruled by the Lord's Divine Providence; and if the thing is too hard to be decided by a man's own rationality, it must be brought to the truth flowing immediately from the Divine principle, and wisdom will be given.
