Commentaire de citation sur Jérémie 35:6

to the house of the Rechabites The sons of Jonadab the son of Rechab, and they were of the sons of Jethro.

על כן לא יאכלו בני ישראל, the children of Yaakov adopted this prohibition for themselves in commemoration of their father whose thigh muscle had been injured.

They are described as loyalists par excellence in the Book of Chronicles. Moses recorded the custom of the Israelites not to eat this organ as one of the 613 commandments.
