He that delicately bringeth up his servant from a child shall have him become his son at length.
– Proverbs 29:21
The word for bringeth up means to pamper. The saying seems to intend a negative consequence and would be paired with verse 19. The word for son only appears here in the Hebrew Bible and the meaning is uncertain. It is generally though to intend a negative outcome such as, grief, or weak. If the negative gloss is correct, the saying gives a warning for lack of discipline and proper training of a servant from childhood.
