Gimel = 3, ordinal 3, reduced 3, no final form. Spelled in full, גמל = 3+40+30 = 73.
Meaning
Gimel is 'camel' and one of the seven doubles (g/gh). The Talmud's alphabet-homily reads the letter as the one who bestows on the poor (gomel dalim), taking its shape as a rich man running after a poor one, and it is that reading — not the camel — which the tradition repeats. Its 3 is the first number with a middle, read as the triad of the supernals.
