We have no son, and yet are giving him a name, [224]
We have not yet saddled, and are already mounted (or riding), [203], [264]
We knock in jest and it is opened in earnest, [153]
We know what we have, but not what we shall get, [161]
We learn by teaching, [104]
We must bear our cross with patience, said the man when he took his wife on his back, [388]
We must eat and drink though every tree were a gallows, [147], [333] (See A man must eat)
We must sow even after a bad harvest, [389]
We must suffer much or die young, [389]
