To be a beneficial action for one to take. It behooves him to give his boss two weeks' notice so that he maintains a good professional relationship with her. It would behoove you to call your mother before she hears about your pregnancy from someone else.

Cliché [for someone] to be obliged to do something. It behooves you to apologize to her for how you insulted her. It behooves me to make up for all the help you have given me.
