Devarim 1:31

Verse 31. And in states of defect of truth and temptation, when it has been manifestly perceived how the soul has been supported by the Divine goodness and wisdom as a man does bear his son (or as the genuine desire after good ever upholds truth in the mind) [N.B.—The love of what is good begets and educates truth in the soul, which is as it were its son] in all the changes it has gone through in its progression to its present state.
