Musar do Samuela I 2:19

Another puzzling statement is the reference to "Jacob the small one," "Samuel the small one", "David the small one," in that order. We are forced to assume that the prophet Samuel is meant here so as to justify the order in which the names are listed. Some people say that the reason Samuel is referred to as the "small" one is, because his mother made a "small" robe for him when he was a little boy (Samuel I 2,19). This surely is a very forced explanation.
