seal 卩 (560a) + right hand 又 (52) = ruler

As you can see, this ruler is a monarch, not something for measuring things!

Note how the vertical stroke of “seal” extends all the way down the side of “right hand”.

(The young prince is instructed) “You must accept the seal of state and shake hands with the archbishop before you can be enthroned as the new ruler of the kingdom.” / [No pronunciation needed]
