Final answer:
According to Tevye in "Fiddler on the Roof," Lazar Wolf, the village butcher, has asked for his eldest daughter Tzeitel's hand in marriage.
Step-by-step explanation:
The character who has asked for Tzeitel's hand in marriage according to Tevye is Lazar Wolf. In the context of the question, this situation is from the musical "Fiddler on the Roof," where Tevye, a Jewish peasant in pre-revolutionary Russia, has three daughters whose marriages give rise to the story's central conflicts. Tzeitel is his eldest daughter, and Lazar Wolf, the wealthy village butcher, is the one who approaches Tevye to ask for her hand in marriage, much to Tevye's initial discomfort and surprise.
