“If he relies on his wisdom and ingenuity, his physical strength and his own efforts, he will labor in vain, his strength will fail, and his ingenuity will be inadequate to achieve his goal, as it says in Scriptures: ‘He traps the clever in their own cunning.’ (Iyov 5:13); ‘Again I saw under the sun that the race is not to the swift, nor the battle to the mighty, nor the bread to the wise.’ (Koheles 9:11); ‘Young lions are poor and hungry, but those who seek G-d lack nothing that is good.’ (Tehillim 34:11).” ~ Chovos Halevovos
