Jacob got the better of Esau, we say, because we’re using a worldly standard to compare their rewards – in this case the ‘dollar’ value of a plate of stew versus that of a substantial inheritance.  But Esau wasn’t stupid: his reality at the moment was an overwhelming hunger, and that changed the equation.  To someone dying of thirst, a drink of water is truly more precious that diamonds and pearls.

Jesus notes the blessedness of those who hunger and thirst after righteousness, that is, obedience to God’s will, because they value the same thing he does.

The final temptation in the wilderness was the whole world versus obedience to God’s will.  It wasn’t a sacrifice for Jesus to choose obedience, because of his own hunger.
