Melech

[Jack]

Why do people use the term Melech for the Rebbe? Not Melech Hamashiach, just Melech? Does it have something to do with Malchus being the seventh of seder Histalshlus or something like that {just my own mind conjuring up an explanation}?

[Bittul]

Ask R' Yekutial (Cuti) Rapp, he's good at things like this.

[mendelp]

Man malchei rabbanan.
