4394/4375, the rectified Hebrew comma, is a small 13-limit comma of about 7.5 cents.
When octave-reduced, 4394/4375 represents a difference between a stack of three 13/10 against one 35/32.
Theory
Tempering out 4394/4375 alongside with 3136/3125 sets the rectified Hebrew temperament, which is a 13-limit extension of didacus. The presence of 4394/4375 being tempered out is the defining factor which specifies the temperament as Rectified Hebrew.
The comma is tempered out by the following vals: 72, 58, 53, 130, 111, 19p, 34d, 19e, 77, 38df. In addition, it is tempered out by 353edo, where it is connected to a proposal to reform the Hebrew calendar, and where it takes its name from.
