Heh's square-script form leaves a small, deliberate gap where its left leg meets the roof stroke, a detail a trained sofer preserves carefully rather than closing up, unlike the fully enclosed letter Cheth, discussed elsewhere in this atlas, which looks almost identical to Heh but for that gap and an unbroken left side.
A widely repeated homiletic teaching, common in Chassidic and popular Jewish teaching on the letters, reads the two shapes together: Cheth's total enclosure is likened to a person sealed into wrongdoing, since the Hebrew word for sin, cheit, begins with the same letter, while Heh's open gap is read as the narrow way back always left open for repentance, however far a person has gone. Heh also occupies two of the four positions in the tetragrammaton, the four-letter name of God at the centre of Jewish reverence for the divine name, and Kabbalistic literature reads its double appearance there, once with a plain vowel and once as the name's closing letter, as marking two distinct aspects of divine revelation, a theme separate from the letter's place among the Sefer Yetzirah's twelve simple letters, covered elsewhere in this atlas. A sofer must reproduce Heh's gap precisely, neither closing it into a Cheth nor widening it enough to be mistaken for a different letter entirely, one of several small proportional judgments that make Hebrew scribal training a matter of years of apprenticeship rather than simple copying.
